EFI vs. Carburetor

Which is right for you EFI or Carburetor
Episode 525 Autorestomod
There are many efi kits out there. And if you want us to review kits, leave a comment in the section below.
For arguments sake we will be using the Holley Sniper Holley Sniper 550-516
Holley Sniper EFI Self-Tuning Fuel Injection Systems
$1,200.00
Basic system without pump and enough fuel line to get back to the pump (more on that in a second.
Pump
If you are “mainstreaming” in your car choices (Mustang, Camaro, Chevelle) There are tanks specificly set up for EFI. The pump flows at 255 liters per hour or roughly 67 gallons per hour.
Tank specific pump (Mustang and Cougar Camaro Chevelle) runs $619.00
This is tricky. To return or not to return fuel? While Holley states that their 650 HP system does not require a return, we’ve read several post on the Holley site that says it does require a return line. Even the in tank pump shows a return line.
We’d recommend upgrading to 3/8ths inch fuel feed line and a minimum of 5/15th line for the return. We’d also go Stainless...Yes you can bend nicop, go ahead, spend Right at $2000.00 for a system then cheap out on fuel line.
NPD has stainless lines for the Mustang Camaro and Chevelle for
$100.00
Plus having to flair fittings for connecting the barbs to the fuel hose.
Or you can join the zip tie brigade and use the modern fuel hose and connectors provided in the Mater Kit to get the job done.
Weld in the bungs anywhere from a couple slices of pizza and a cold bear to a couple hundred bucks
We’ll call it $100 to be safe.
Plus $150 in miscellaneous (pizza, beer and piddly parts like filters)
All in on a Holley EFI
Right at $2,200.00
Carburetor.
Biggest issue used to be sizing your carburetor.
There are calculators for that now. Though my experience has been to go about 100 cfm over the calculators recommendation. Also, different cam and heads will effect that.
So, we’re specing a 650 cfm carb. The two most popular for street are the Edelbrock and the Holley.
Holley 0-80783C 650 CFM Classic Holley Carburetor is on backoreder as of filming so we moved over to the 670 CFM Avenger.
Cost for the Holley 670 Avenger will be around $520.00
Cost for the Edelbrock 650 1906 will be $420.00
If you are bare with no intake, you’ll spend between $200.00 and $400.00 for an intake for the car. This isn’t an intake comparison so we aren’t going to argue that. That same money can be added to the EFI
Good quality fuel pump:
$85.00
NPD has stainless lines for the Mustang Camaro and Chevelle for
$100.00
Tuning Kit will be a really good idea. $125.00-$177.93
Plus $150 in miscellaneous (pizza, beer and piddly parts like filters)
$1,000.00

Two issues that weren't addressed: replacement parts for EFI. I have heard so many people complain about the EFI computer/controller dying after 6 months or a year, trying to buy a replacement, and being told that they had to buy the entire kit to get a replacement computer. Not sure it that is still an issue, but if so!! 2nd: When an EFI system dies, you are not going anywhere, and there are lot's of potential points of failure on aftermarket EFI. I have never had a carburetor fail so badly that I could not drive the car. I love how well my car drives with EFI, but that is a factory EFI that has been long term tested by Toyota, and it's reliable as can be. On my hot rods, I prefer carbs. The benefits of lower cost, available replacement parts, and not being prone to sudden failure made that decision for me.

[@danielgustafson8509]

Not really an issue for most. Everyone I know that runs them has zero issues, the whiners on FB and the forums are likely most of their own problem.

[@hotrodswoodshed7405]

absolutely 💯

[@hardball107]

I've installed 4 systems, 2 Holley, 2 Fitech. All have been running for years without a problem. Those people complaining need to check their grounds and improve their wiring skills. I have seen many systems with butt connectors, rust under grounds, tape wrapped around connections, no fuses, ect. I made my living working on vehicles since the early 70's and I started with injection around 20 years ago. Anyone complaining about sudden failures and running problems needs to reevaluate the installation he's having problems with. Most FI systems last the life of the vehicle, run with perfect mixture even at different altitudes, increase mileage and power and will allow or cover up problems like over camming an engine. Remember back in the day when engines lasted only around 100,000 miles if you were lucky ? That's because most of the time people didn't even know what a choke pull off was or how it worked and there are even less now. As far as replacement parts go these systems use stock GM or Ford sensors available at any parts store.

[@jamesharris2615]

The key to these systems working properly... GOOD WIRING. can't stress that enough.

[@ivanbadillo4909]

I completely agree with the original comment. Also you need a wide band oxygen sensor to fine tune a carburetor as well.

[@jamesharris2615]

I put the Holley system on my car for a little less than $1500... Worth EVERY penny spent. And you don't have to purchase a new intake. Dual or single plain works just fine. I like what you guys do.

[@AutoAli]

My 66 is running an Fi Tech EfI and I love it. I started with an external pump (not a fan.) then moved to the Holley in tank sending unit that was $300 and I’m running a return system. All told with NiCu lines, AN fittings, pump, and EFI (clearance find at summit) were around $1200 ($1700 not on clearance). In my opinion is very subjective. The 66 is awesome with EFI (and I’m sure I’ll convert other cars I restore) where as I would never do the conversion on our MGA or rat rod.

[@AutoRestoMod]

[@aaroncake]

Good discussion that focused primarily on the "carburetor replacement" type EFI setups. These setups definitely have their place (I'm trying to convince my brother to put one on his Continental) and are an easy way to get many of the benefits of EFI without needing to really tune it. But the real advantage of EFI is when you get into the proper full standalone systems like Haltech, Electromotive, or if you are more DIY, MegaSquirt. The learning curve is much steeper and the cost to implement can be much higher however the benefits are well worth it. Multipoint sequential injection, boost control, auxiliary device control, high resolution tables, plenty of corrections and engine protection. The ability to control every aspect of the engine. In a way, these carburetor replacement type systems are akin to TBI with a fancier controller. A good stop gap with some real improvements and advantages that will always fall short of a more modern system.

[@mrknebel475]

I run an EFI and I must say the ease of tuning is incredible. You don't have to change any jets, no gas mess...no hot engine to deal with. I also run timing control and its just as easy to change timingcurves on the fly

[@HO-palMNTSC]

My ford LTD runs with the std Motorcraft carburetor! Very reliable, but underestimate the 302v8 capacity, and this is the reason I will replace it by a Holley Sniper EFI 🤩

[@BareRoseGarage]

Biggest advise I have in an EFI conv, buy EVERYTHING from 1 company. Tell them what you have, and buy it all from that 1 company. Saves the hassle of getting parts that DO NOT match up, and if it doesn't match up, it's only 1 company you have to deal with to make it all right. Other then that, I'm a Carb Guy. I put manual choke carburetors on everything unless it has a "power adder". Then I let the computer do all the "on the fly" tricky stuff. I'm backwards in that. I like carbs on my daily, and EFI (ecu's) on a Wild Ride.

[@AutoRestoMod]

Makes sense!

I will need to say I did upgrade to 1990 Ford F-250 460 EFI plow truck for the winter time cold start . For a winter EFI is king .

[@AutoRestoMod]

Agreed.

[@67Stang]

Planning to put a Holley Sniper Autolite 1100 on my Mustang if it ever gets here. Decided to go this route for a couple of reasons. The first was looking to the future. When I am gone and the car goes to a family member, none of them are really car people. So they will need to take it to a mechanic. As yall mentioned, most current mechanics don't know what a carb is let alone how to work on one. So it will make it easier for them in the future. The second is the other thing you mentioned. It is just easier to tune. I like the easy button. I am replacing the carb and distributor for a complete system. The real downside for anyone at this time is just getting the parts for an EFI conversion. Mine has been on back order since March.

[@edcucchiarella7994]

That is factor with me, none of my kids ever had a car with a carb.

[@scottwiest3267]

Holley Sniper EFI. Looks good, runs great. Handles all the power I can throw at it. Timing adjust at your finger tips.

[@AutoRestoMod]

Good stuff for sure.

[@dannybarlow4256]

Never buy a Holley kit too many issues

[@andrewfrantz6109]

The cost was only about $1300 for me to run a sniper, but I started with a return Sniper, sourced a GM baffled fuel tank from a newer model of my truck and an AC Delco Fuel pump and sending unit. That setup ended up costing about half what Holley charged me. Had to separately source filters and lines. The 10 micron filters cost a fortune but there is a GM canister filter you can use if you cut the barbs and use AN6 compression fittings. This was for a square body truck, so I have good parts selection.

[@AutoRestoMod]

Thanks for the heads up and tips those are awesome.

[@Jon-Bar]

I’m running FITech and an older FASTEFI. I like them. I don’t recommend external pumps, but FITech makes a nice submerged pump you can put in the engine bay that feeds off your stock low pressure pump. Works great. Re-parts: Most parts you need are fuel pump, filter, injectors (which are usually off the shelf and easy to find at a parts store) and the ECU. If you have a bad ECU after warranty, there’s probably a better model on the market anyways, so buying a new kit isn’t a bad idea. There’s also port-injection kits that aren’t all-in-one that are effectively just an ECU.

[@AutoRestoMod]

Good points. I like the Fast, but that can can be a bear to hide unless they have made it smaller.

[@reyzapata9375]

Edelbrock & Holley is Ok. In my 70 Impala I’m running the Original 4bb Rochester Carburetor. Never had a problem with it. And it’s easy to adjust.😇👍

The Rochester is a good carb.

[@reyzapata9375]

Thanks, we love watching your videos. And The craziness you guys do.😂🙏🏽😇👍

[@mkspeedlab9335]

I upgraded to a Holley Sniper on my 72 Mach 1, and some things I have learnt. You need to make sure everything is in really good shape to start. A carb doesnt care about an exhaust leak, the EFI does. While you can do a lot on the handheld, you are definately going to want a laptop if your planning on tuning it yourself. And while I didnt have any problems, you need to really pay care when routing wires, and make sure you follow the wiring instructions to a t. And the self learning is a little bit of a misnomer, it tweaks it, but you need to get things in the ballpark. And timing doesnt learn. I relate it to a carb, the EFI basically learns the jet size. The rest, you will have to tweak yourself.

[@AutoRestoMod]

Thanks for the heads up.

[@tbiker99]

I've woorked on cars my whole life, but the only carborated cars I had was when I was a kid and dad tuned the carborators. I've almost exclussivly owned EFI cars and my motorcycles had carbs but they just worked. I didn't learn carborators until late in my 40s, when I got a classic Ford. I won't lie a couple of little issues almost made me put EFI on my old Flathead. Finally got it dialed in and it starts amd runs good. Mountain driving is another tick for the EFI systems. A car with only a 100hp can't afford to lose much when you start climbing 4-5000 ft.

[@AutoRestoMod]

LOL you know that's right!

[@GNaron]

I'm a Edelbrock Pro Flo 4 guy. The PF4 is a true port injection system and comes with intake and distributor for around 2 grand. The spark is controlled by the PF4s ECM. Most of the sensor are off the shelf parts from any parts house.

[@AutoRestoMod]

We'll take a look at that one in more depth.

[@GNaron]

@@AutoRestoMod I made a couple of the system. Because people kept asking what kind of carburetor is that? Both on KZbin and at Cars and Coffee.

[@hardball107]

Long story short I've been installing or helping people install these systems for years now, mostly Fitech but I did do 2 Holley units. I use hard line and flair, sometimes I use the Little Gem fittings that have compression fittings with AN on the other side. Flexible line is used for vibration isolation only. I have started converting standard in tank pickups to submerged pump systems, not to difficult with simple fab skills. I run a lot of grounds and seperate circuits with anti-ox compound on everything and use weather-pack connectors everywhere else. No scotch locks or tape, just solder and shrink tube. There are oxygen sensor bungs that use exhaust band clamps if you don't have access to a welder, works MUCH better than a horseshoe clamp. Done properly FI systems improve power and mileage, are more reliable and increase engine life most times doubling it. Remember when a cars engine was worn out at 100,000 miles ? You could thank carbs for that and people nowadays understand even less about them or their proper maintenance and there's not a carb out there that will compensate and adjust it's mixture as you drive as you travel from the seashore up into the mountains and back.

[@AutoRestoMod]

You are right.

[@armygreenfj3924]

Theres just something about carburetors that i like more…Its old school and they are extremely reliable and easy to fix..If you run a edelbrock carburetor the chances of part replacement is much easier to get at your local store. With a EFI if the electric module goes out chances are you can’t get that part right away. You also have to worry about your O2 sensor going out. You have to make sure electrical components dont get EMF which can throw your EFI system run funny or not run at all. However I believe they are great systems once dialed in as long as those things I mentioned above dont go wrong. I may try it some day. But my AVS2 is running great so far

[@slick-px4pq]

I have the MSD system, the instructions say to NOT use hard fuel lines. Something about cavitation. I'm assuming it has to do with the pulse width modulating fuel pump. Also, another option for full timing control is the distributor from Progressive Ignition. It connects to your phone via Bluetooth and allows you to make changes to the timing curve while the engine is running, in real time.

[@AutoRestoMod]

If the instructions say not to do it...I won't...mostly.

[@theinfernalcraftsman]

When I was a tech I had to deal with computer controlled carbs and other oddities of those years and I don't have the pertinence to adjust them anymore. I now much prefer FI where it can cope with weather and altitude changes and has somewhat of a self adjusting mode to it's software which is getting way better these days. I don't miss carbs or points or even distributors for that matter. In those days to do an EFI swap it was a matter of pulling a harness and throttle body from a GM vehicle then burning a chip and hope you got close then keep fine tuning it from there. The new ECMs make it far easier.

There is a lot to be said for fire and forget.

I'd rebuild the Motorcraft and see what it does, the kit is cheap compared to a new carb.

[@jessemiller3001]

I would go Edelbrock... Buy the power rod, spring, jet kit, and you can tune that thing to perfection. It will take a month, or a couple afternoons if you have an LM-1 air fuel guage.

[@FabriceClosier]

Happy with my sniper first gen installed in 2017 on a 351c 4v. Pricy yes, but so much better than any of my previous carbs. I can now also stay in my garage during cold starts without dying for instance! oh and yeah, no more cold starts pumping circus! It simply idles bits higher on its own. Hot starts that were driving me nuts on my cleveland: boom, gone, not even 1/4 turn starter and there she goes! Smooth and responsive at all rpms. Install is NOT done in a weekend as they say on classic cars, at least if you want it safe, clean and well installed, all electrics nicely routed and protected. Brackets needs be fabricated etc.. count a few weekends. A welded bung is a must. The thingy they provide is a good bracelet for your gf. On 71-73 mustangs, prolly torinos and many other fords of that era too, you can replace the top vent hole by a sending unit, it's the exact same hole and use that as a return. There is enough space on the plate for a second vent tube too, it's like redoing the 71 429 sending units for Rochesters with return lines, but placed on top. I run the kit pump and it makes zero noise if properly fitted and insulated, steady pressure too. So no need for an expensive new fuel tank and extra pump really. One of the most returning remarks i read about people returning to carbs after their failed installs is that the system is not forgiven as a carb could be: it will not hide or mask anything about the engine condition, the exhaust, the wiring or pardon bad install. It's either it works perfectly or something is wrong and it runs bad or not at all. One thing is certain for me, on both my mustangs: no more carb! Best investment I ever made in 30+ years mustang.

Carbs are also annoying if you use your vehicle for long trips with a lot of altitude changes. Performance definitely will be affected by varying altitudes. I am considering putting an EFI on my 67 Mustang to make time ups a bit easier.

Yes. They are not as adaptable as the the EFI as far as fuel curves. One reason we are considering it for the Falcon if we do a supercharger.

[@chuckdavis3587]

I'm 40 years old, and owned a carburated car for over 20 years. I read the books, watched the videos, bought the tuning kit, read the spark plugs, asked the older generation, and i've come to the conclusion that it is always a compromise. The carburetor cannot adjust for air density, temperature, and it has no feedback other than me feeling something wrong. My family is also over the gas smell that I cannot seem to get rid of no matter how lean I tune it. I'm switching over to a Sniper system this winter. I got the factory refurb unit for $800, and the in-tank pump for $400. I should have another $200 in miscellaneous items to finish it up. I'm ready to hit the key and not have to do the "Biff Tannen" dance with the pedal to fire it up depending on if it is hot or cold, and how long it has heat soaked.

[@jeromethemechanic6871]

[@danlong6947]

I'd say to tune a carb correctly requires the cost of an O2 sensor, but the EFI includes an O2 sensor.

Tuning the carb takes a bit more than that. And we tuned them in the '70s without the O2 sensor.

[@HotRodDave]

I want to do a blow thru turbo with the holley sniper but I want to run e85 and the say it is a no for e85 so I will go carburetor

[@danielgustafson8509]

Great video, but a little weak on the description of a retrofit EFI. The EFI system need clean noise free power I upgraded to a 3G internally regulated 180 Amp Alt. There can be no vacuum leaks after the EFI unit and absolutely no exhaust leaks upstream of the O2 sensor. You really need to know how to run clan wiring. It helps if you understand that the spark traveling through a plug wire, coil or distributor creates a magnetic field, that in turn can INDUCE an electrical current in signal wires that go to the sniper. Rust and gunk commonly found in old tanks and lines will plug up the fine fuel filters needed for EFI. Heat is bad for electronics - coated headers reduce engine bay temps significantly. Edelbrock makes a 1\4" thermally insulated gasket spacer (9265) - keeps a lot of heat out of the TBI unit itself. Return lines are ideal - helps keep fuel cooler and should eliminate vapor lock issues. I used the HyperSpark ignition with my install and ran new 3/8 copper/nickel alloy feed and return lines, AN fittings, filters and check valve, Tanks Ink 22-gallon tank, Pump and Sender, and the Base Sniper - $3300 before tax on at todays prices. That does not include the 3G upgrade. Another $350 for a professional tune, $500 for professional Tubing straightener and flaring tools from Eastwood. As far as miscellaneous crap - probably a few hundred in quality copper wire, nylon weave split sheathing, ... Its a journey, but fun!

[@AutoRestoMod]

We weren't going to get into the details. This was an overview. If we go detailed it will be because we have an EFI in house and are installing it. Good points!

@@randysrestoration I used a piece of hose to put the intermediate shaft back in and just let the old one stay in the pan. I ended up pulling the motor last winter mainly to change the intake to a 4 barrel and put a timing set in it. Power is relative, I grew up driving a 2.3l ranger lol

Always check the ignition first. Unless fuel is shooting out of the vents like Old Faithful.

[@AutoRestoMod]

LOTUS is right, ignition, timing and fuel are tied together.

[@edcucchiarella7994]

I am a long time tech and own a 66 Ranchero and know carburetors well and feel you missed one thing. I live in CA and have been having issues with the gas eating up power valves and gaskets as well and the fuel evaporates over a few days in the bowls causing hard starts and there is the vaporlock issues that a phenolic spacer helps with. If I go to fuel injection I have been looking at the Edelbrock pro flow 4 and using their fuel sump as there is no EFI tank for my car and it does need a vent return line to the tank / filler neck. Is the rest of the country dealing with ethanol / oxygenated fuels issues?

[@I_like_turtles_67]

I have a 67 fastback that I am converting to efi. Terminator system. But I am installing a flex fuel sensor I the system. So I can run e85 or premium in my sbf. In doing so. Everything will handle the issues with e85.

I think that the CARB enforced stuff in Cali is far more wicked to fuel systems than in the rest of the US> I can remember those issue back 20 years ago and it can't have gotten any "better" for the California enthusiast.

[@2lotusman851]

Hmmm. Let me guess......................The answer is in the book on Holleys that you are going to buy from Amazon.

[@AutoRestoMod]

The power valve will be based off of what your vacuum is under acceleration. Holley has videos on how to pick power valves.

[@Milner62]

Carbs are in the same boat as EFI when. Roke down on the side of the road. You cant go to a auto parts store and get a carb kit, they have to either go to warehouse and get it or order it. Then if dealing with aftermarket holley or edelbrock carb your local parts store for sure wouldnt have it on stock. I have seen this the last few years theough work having to get local part houses to order carb kits for us to re build a carb. For me I'm plumbing a s ioer stealth 4150 on my new 302 build not cause I can't t tune a carb but because I want t to squeeze as much economy and performance I can for my truck. I'm also wa ting to get away from leaking accelerator pumps which seem to be failing every 6 to 8 months due to this ethanol blended fuel.

[@AutoRestoMod]

True enough!

[@randysrestoration]

I installed the beyond horrible garbage Fitech dual quad setup on my 482” FE. They gave me a “deal” Everything you need 1600.00. By the time it was said n done trying to make it work i had spent 5k. At that point i pulled the plug lost the entire 5k plus a boatload of time. Never again if free. I have found buying a late model donor vehicle complete and using parts needed selling whats not needed giving one OEM efi is the way to go. I have purchased 4 complete donors for far less than 5k spent for JUNK. Then i get free big brake upgrade, low mile engine, transmission all electronics plus little parts.

I have a SBC ZZ5 motor... MSD Atomic, Fitech, and then sniper. Nothing could get this car to run right in closed loop cold start mode. The car would stall and fall on its face I would have to sit and baby the gas till it got up to temp and then could drive it around. 1 of the manufacturers gave up and sent me a whole new kit past warranty which I sold to convert to a carburetor. Went with an Edelbrock AVS2 and I have the damn thing dialed in better than the EFI. Not saying EFI is bad, just a shame it didnt work or was as easy for me as they make it on TV. For the record, I'm a "young" person - going to the Edlebrock was the first time I put my hands on a carb so I was doing EFI out of the gate with my car. Wish I or the manufacturers could solve the problem, but after 5 years of fighting and trying I just wanted to drive and enjoy the car

[@AutoRestoMod]

That cold loop start issue is where we are most concerned. There is a lot that the computer has to do to keep the engine running under cold start. The OEMs spent lots of money to get that right, money that I worry most Aftermarkets are not interested in spending.

[@michaelcannizzo1076]

@@AutoRestoMod in my experience it is solvable on something really robust like the Holley Terminator, maybe even the Sniper; but by time I got to the sniper and I couldn't even get it to fire right with an MSD Billet HEI, I was simply done and almost chucked the whole thing against the wall. I'll say this much, living in NYC I drive my car all the time long as there is no snow or salt down. I have a wideband O2 in the car and "tuning" between dead winter and July is a simple rod change from 70x57 rods to 71x58 rods. Thats it, done deal. Not these wild swings. Car does 14.0 cruise, 14.0-14.5 idle and 12.8 WOT its beautiful

Iam having issues with my Holly Sniper on a 66 Mustang. It was installed by a guy that has done a lot of them and has a lot of knowledge. It was installed before the car was done...and is just now getting near complete. Its pretty frustrating...pay that kind of money and it wont even pull itself out of the shop....touch the throttle and it dies immediately . Another very qualified person says the EFI distributor creates electrical interference with the brain of the EFI which is very close. He recommends a plate be installed between the dist and throttle body. Iam going to let the mechanic work on it until he throws up his hands and says hes done. Iam expecting to replace it with a carb.....Time will tell

[@AutoRestoMod]

I know these systems are sensitive to grounds and exhaust issues. I hope he gets it worked out

[@DieselRamcharger]

this is throttle body so your argument is mechanical carburetor vs electric carburetor. This is not port injection.

[@highrx]

Older carb engines in a vehicle that you don’t drive every day ( dump runner pickup ) ? Use non ethanol fuel and an edelbrock set up. One good back fire with a Holley? Yep, you’ve blown the power valve on that Holley. So you’re pulling off the carb to replace the PV and you should do a oil change regardless of mileage on the oil because the oil is now fuel contaminated. Don’t forget too add in the zinc additives to oil. JMO.

[@AutoRestoMod]

Good points. The power valve pop is a little less problematic now. I agree with the oil change in that instance though.

[@Monotachi]

Holley has power valve protection on newer carbs. Also easy to install on an older carb.

I can see advantage of fuel injection, just do not see the benefits for 50 plus year old car. I know my classic car is better maintained and care for then they were new.

I tend to agree.

[@dividingbyzerofpv6748]

Sniper is sensitive to EMI. Sometimes horribly so be it coil, distributor, or alternator. When you install your air cleaner and suddenly your car runs like crap, that is EMI. Very good chance I will be ditching my sniper for a Terminator to get the brains of the system hidden inside the car.

Update you description... 5/15th return line? Thank you for comparing NEW to NEW. Many may mention a swap meet carb to save $. Calculators for carb sizing are OK and get you into a streetable carb most of the time. As you mention in the description, other components really impact a good sizing. What you fail to mention is the value/$ of properly running a carb and resetting. Go to the track and max power is a rejet. Take a trip to the mountains/beach, and you won't be "optimal". (Example summer in Vegas to San Diego or Phoenix to Flagstaff). Most people don't want to mess with jetting and returning (carbs lose their tune) when EFI does it for you. At today's gasoline prices, you could likely get a fast ROI going EFI.

[@AutoRestoMod]

5/16th is the Holley minimum according to the instructions I found online. We did talk about the hassle. But in a different way, Cam and I discuss the seasonal changes, full throttle vs. cruise. It can be a hassle.

🔔😎 You major on minor possible problems. 🙄🙄 EFI is super simple to work on if you have a basic understanding of what each sensor does. e g.
