[@voncilesanders8308]

Greetings Fixd! Just wanted to thank you for 'keeping it simple' for me! I have cleaned my MAF, purchased and installed new plugs, and ignition coils, changed the head gasket, changed transmission fluid/filter, and installed a new PCV Value...Yet the P0301 persists! When the weather permits, I shall tackle the task of removing the ignition coil into the #2 position and see how it goes, ugh. Thank you again and I hope your days are well.

[@colintx800]

Another thing that can cause a misfire is loose camshaft bearing caps. I had a P0302 which every single garage failed to diagnose. I took the rocker cover off and every single bolt could be unscrewed by hand. Tightened up the bolts in sequence and the misfire went away, I spent money on a coil pack, spark plugs, fuel injectors, and compression tester for nothing. Compression was perfect so it's one to check people.

[@devenstone256]

What motor?

[@modeljetjuggernaut4864]

if it was a bad fuel filter, would that not effect the entire combustion process in all cylinders? How can it be isolated to #1?

[@rhuarimacleod4862]

I'm sure an air or fuel leak would effect all cylinders too. I geuss he is assuming you have a diagnostics kit which gives the code p301 which is misfire in cylinder 1. Hope that explains 👍

[@ManuelLeon-gm5im]

​@Rhuari Macleod if multiple are failing what code would it give?

[@rhuarimacleod4862]

@Man p0300 I believe. Commonly caused by a blown head gasket!

Thank you for explaining this, my engine threw this code after I left the air conditioner running for about 5 mins while idling💜and subbed

[@celia3479]

My 04 Prius had been a little off when coming to stops every so often (felt like a standard does when stalling). I thought it was the brakes at first, but kept driving since they were fine otherwise. after a couple weeks of daily driving (and a 2 hour trip over a mountain) I checked it and it threw this P0301 code, drove it to the auto shop and it started smoking on the way there. I changed my spark plugs and coil packs and it wasn’t smoking anymore, but then one day my check engine light came on. I checked and it still had the P0301 on. I’m sure there’s dirt in my fuel line after an attempt at taking the injectors out. I’m not sure what else to look for since it wasn’t the spark plugs/coils and the smoke and I dont have the means to tow it. The battery is currently dead and the last time I drove it, it started barely accelerating to my driveway and sounded very rough.

[@NAGIUXS]

It’s 100% a Blown head gasket. Very common problem on almost all Prius. Anything else is a waste of money and time. Happened to me

[@marcomartorana9506]

Thank you! Solved the issue on Nissan Rogue 2011, it was the inition coil. detected with an odb2 scanner, switched the ignition coil with the cylinder number 2 and it returned me the code p0302. Buy a new one for 25 box.... Priceless your suggestion!

Original owner of an ‘07 Prius. Ignition coils in two of them were bad and the other two were less than good but just ok. Checked on a meter. Plugs were light to dark grey after 40,000 miles. Changed all plugs and coils. $750. Labor was $150 included in the $750. 250,000 miles on it. Passed CA smog after a 100 miles of driving. Now I can drive it another two years and then make a decision. 👍

2010 Buick Lucerne. I changed plugs 18000 miles ago. Car started to run rough. Progressively worse. Inniva scan tool said misfire on cylinder 1. Never got a check engine light. Not sure how that was. Basically checked resistance of plug wires. Cleaned mass airflow. Then found out it was a bad plug by swapping into cylinder 4 and it misfired there. Plug looked fine .

[@thesetruths1404]

Hi I have a 2007 Liberty 3.7L V6, 117,000 miles. Owned it since 67,000 miles. It operated perfectly for the first 30,000 miles and then it started getting a #1 Cyl misfire code P0301. It also seldomly gets a #1 cyl fuel injector circuit open P0201. It must be a very mild fault as the misfire freeze frame data shows it always happens at less than 350 rpm and when cleared it comes back immediately at next startup, cold or hot. So it seems to only happen once on startup as its moving up to regular idle speed. The miss isnt noticeable when driving or idling. Its getting 15.5 mpg fuel mileage. Doesnt burn oil. Doesnt smoke. Has great power. I've changed plugs and coils but no difference. Cleaned air intake, air filter, and ran cleaner through system. I've cleaned and inspected the injector plug and all wires but no difference. Dry / wet compression test of #1, 3 and 5 cylinders all read good: 160 / 175 psi. I'm wondering if there's a mild wire defect for that injector, or just a flakey connection somewhere. Has anyone tried to use a new set of compatible gauge wires and run them to a place closer to the injector control? I can't see where the wires go though. I'm not sure if I should just live with this, or troubleshoot it more. I don’t care about the engine light as we don't have emission requirements. Now that I know the compression is good, I'm not so worried about it. Any suggestions of what to do next? Thanks!

The quality of fuel is significant. Maybe a higher octane would help your vehicle, or try not run it on corn cobs? I would suspect the wire set first damaged by heat under the hood, and maybe fresh spark plugs correctly gapped. ..the spark plug wire is dead at 300+ Ohms. ..and the wire from the coil should be zero Ohms. ..you need good spark, maybe the coil is weak?

I've changed plugs and coils, cleaned the EGR, EGR/intake channels, and cleaned the throttle body. Not quite sure what it could be. Sometimes the code goes away if I don't clear it.

[@fixdapp]

With a rough running car it is always best to diagnose the issue first. Most of the time a quick scan of the car and getting the related fault codes will point you in the right direction. You are definitely on the right track to diagnosing an engine misfire/rough running issue, however due to the complexity of most newer automobile engines, you will need to find out what fault codes are being thrown then reassess. For example, if it is a fuel supply issue, you replaced the fuel pump but could have an issue on the injector side. This could be a leaking injector, dirty injector etc. Give it a scan and check faults.

I got a PO302 code on my 2012 Ford Transit. I checked my oil and was low, so I filled it. Then I switched 302 with 301. Started it up and it ran good. So I was assuming (hoping) the problem was oil. I cleared the cobe and all was well for 2 months. Today I started with engine banging and poor idle. There were NO codes on my dash. Now I looked at my phone and was getting an issue on 1 & 2. I couldn't understand why my dash wasn't reading a miss fire in one. It onley shoed up in 'history' My friend works on cars said my FIXD reading on my phone probadly showed this fault right after I originally switched parts. I thought it would automatically show up on my dash as an alert. WRONG! The past history stays on the phone for your history reference. I don't know if I explained this well. $180.00 later with 4 new injector and I am running great with no laber costs. This may require a bit of thinking if you are not savey with codes like i'm not. ALSO. Auto Zone informed me the injecter I bought have a lifetime warranty.....I asked why the injecters in the van weren't got for the vehicles lifetime. They said they were a ford product, they see it all the time. Oh well.

[@Zeberka767]

Thank you for the video. I have a misfire code on one of the cylinders. After doing various diagnoses, it has been definitely determined that the issue is with a bad ground wire on the fuel injector connector on the cylinder with the misfire code. I replaced the entire ground wire for that cylinder with the misfire code from the fuel injector connector all the way to the ECM just to be sure, even though I didn't even see a broken or chewed up wire. This didn't resolve the issue. The car has a V6 cylinder and I also diagnosed the other 5 fuel injector connectors. The ground wires for all those 5 fuel injector connectors are fine. Since replacing the ground wire didn't resolve the issue, is there anything you can suggest I try out at this point? For the time being, as an alternative method, I decided to splice and share the functional ground wire from the adjacent cylinder. In other words, I now have two fuel injector connectors sharing the same ground wire. This method has worked and has resolved the misfire issue. However, my concern is if this method is an acceptable resolution or is there any type of downside or hazard this could cause? Thank you!

2009 tahoe hybrid 6.0. P0301. Oil all over spark plug threads and ceramic tab. I cant figure out if its rings or valve seals because I cant do compression (dry or wet) because I dont have the tool to tell computer to crank. Any advice?

[@fixdapp]

Oil on the spark plugs can be a few different things. This can be caused by a faulty pcv allowing too much oil back into the system. There are a few different tech bulletins addressing these issues. If the oil is in the spark plug wells, this can be caused by a leaking valve cover gasket, and/or o-ring seals. If the above listed are not the issue, a leak down/compression test is a good place to start. You will need a cylinder leak down tester and a compression gauge. This can be difficult to do and you may need to find a local repair shop to do this for you.

[@yourname7267]

@@fixdapp yes. I grew up in a shop from 10yo. I changed the valve cover with faulty PVC to the new gm part with new gasket, Didnt help. I've done all the research possible. I've found the bulletins. I know how to do leakdown and compression tests but it's a hybrid so I have to have a tech2 scanner and place the computer in crank mode because it wont crank otherwose being that its hybrid. I just dont have the tool and GM will charge me easy 500 to test. Its leaking on the spark side threads. I've heard there is no spark tube gaskets because they screw right into the head. So that leaves valve guide seals or ring blowby. Guess I have to invest in a tech2 scanner :/ If you can reply and tell me the likeliness of it being ring problem or gasket problems base on symptoms I'd appreciate it.

Does anyone know what would be going on with my truck? I have a 2010 Dodge Dakota with a 3.7L V6 engine. It has a check engine light that has been coming on and off for a little while. Whenever I start it up it makes this puttering sound that seems to get better as i drive it. I have also taken it to a shop and they told me that Cylinder 1 is misfiring but they are stumped on the cause of it. They are telling me that these issues may not even be connected and there might be 2 things wrong with my truck. They are recommending I replace the engine as trying to find out and fix whatever is wrong would not be worth it. What should I do? Sell my truck off as is for whatever I can get for it or try to fix it???!? A new engine plus labor will likely be at least 4 grand :(

Change mechanics for starters...in the end if you dont get it sorted out and get a new vehicle DON'T buy another dodge...unless you like continuous wiring and electric issues

Ha ha ha picture of the spark plug at 1:13 is upside down

[@ladytnt491]

I think my issue is beyond all of those components. I replaced my fuel injectors, spark plugs, coils, PVC valve, upper intake gasket, and I still have a po301 code.

[@dannymar2806]

Same here..new wires.. plugs..injectors..cap ..rotor ..coil..and fuel filter...then I found a vacuum leak and thought I solved the problem. Nope.. still getting a 301code. Need to check my o2 sensors next I guess. Maybe pull the throttle body for cleaning...but I'd think that would affect all cylinders? One guy here wrote that he found a bad/no ground wire to his no 1 fuel injector ..youd think the it wouldn't work at all if no ground.. but mine only seems to miss at a light or stop sign..in gear... trying to relearn the idle valve or whatever it's called but it won't go into that mode...maybe the valve is gummed up..hell I don't know.

[@ladytnt491]

You may need a air compression test for your cylinders

[@dannymar2806]

@@ladytnt491 I did that too ...early on. Funny though..it actually read a little higher than normal compression. I wonder if that means something like a bent pushrod on the exhaust or something? Or could of been an err on my part...but there was definitely ample cylinder pressure to say head gaskest and the rest of the motor was okay

[@dannymar2806]

Problem solved! After removing and cleaning all components of the throttle body...including the idle control air valve (which I would highly recommend on any vehicle as old as mine ..2002) I redirected my attention to the 301 code number one cylinder. Thinking to myself this has got to be something simple since the compression test showed good. Pulled the injector and found that the o-ring was cut. Also noticed the fuel rail was not sitting centered on the rubber seat. New o-ring and adjusted the seat and she idles perfect now...including in gear. No more stalling during acceleration either. Used assembly lube this time around to seat the fuel injector...slipped in like a glove

Great video easy to understand thank you very much 👍🏼

[@Devilxxksa]

The problem is , when I hit full throttle and rpm reaches 6-7 sometimes and not always engine light flashes and the car become weaker and after 30 seconds everything get back to normal and Engine light go off again . P0301 and sometimes > P0301 P0300 P0305 . I replaced Cylinder 1 with 4 still showing me 1 , I dunno what to do I don’t want replace something for nothing . Thank u for your video

[@marweazy1]

Devilxxksa let me kno if u fixed it

[@aaronwilcott4561]

Devilxxksa......im having that exact same issue.Did you ever get it fixed and if so,what was the issue?Thanks

[@iangraham6730]

What car is it? Year, engine, fuel type and capacity? Try swapping your fuel injector (if petrol) if still the same, do a compression test, that will rule out valves and rings, also check your wiring to the coil..

[@lalolalo1233]

lol it's the MAF.

[@aaronwilcott4561]

Well my issue ended up being an ignition coil. Replaced it with a new coil and problem went away briefly. Same problem came back and realized I had gotten another bad coil again!That's 2 bad coils in a row.....what are the odds🙄I'm not complaining because it could have been a lot worse!!!!

Can't find cylinder 1 on a 2000 impala 3400 sfi motor

[@tobiasmendoza8121]

I found 3 and 5 cylinders but can't find cylinder 1 on 3.4 liter engine

[@fixdapp]

If you are standing in front of your vehicle, cylinder one is located on the back side of the engine basically under/ bottom side of the alternator. The wires on the coil pack (located on the top of the engine with the spark plug wires connected to it) are numbered from the factory. Follow the labeled number one wire from the top to the back side of the engine, this will locate the #1 cylinder.

My 1991 3000 GT is misfiring. Please help.

[@richpurnell3845]

What Code are you getting? Did you watch the video?

[@roncon1180]

No need to get codes for misfire. Turn your car on. Open the hood and remove one spark plug cable, if the car gets worse, plug it back in, that’s not the faulty cylinder thats misfiring. Keep doing this until you remove a spark plug cable and there is no difference in the performance of the car. This means that that cylinder is the one misfiring. First thing you do, check the cable/coil (whichever one it has), make sure it’s not broken and shorting out if it looks good continue. Second, check for spark, if no spark you’re gonna check your distributor cap (if it has one), if it has a coil and no spark, it’s gonna be a bad coil. If you have spark, take the spark plug out and check for any defect. If it’s fine smell the bottom of the spark plug, it should smell like gasoline. If it does not smell like gas, it’s your injector. If you check all these and everything is fine your problem will be a vacuum leak or a valve in the cylinder head is stuck open (not likely).

[@amycharpentier5404]

Okay so here is the problem! I have a 2002 Toyota Corolla. Getting the code so I change the fuel injector on 1, changed all spark plugs, and coils are good because I switched them and the codes didn’t change. Engine is running rough. Shakes when I get to a stop or just idling. Mechanic said the cylinder may just be fucked

[@powerstuffup]

Ohh.. so what ended up happening??

[@PhuckHue2]

cylinder is fucked

[@909fresh]

I replaced all 4 coils and plugs and still get the p0301 code 🤦🏿‍♂️ maybe it's the fuel filter
