Yes I was informed of all of that when I went to the Racing store. It appears I have a pree vortex reburn. And it was giving me problems because the previous owner had installed it incorrectly. So this week I am doing a complete teardown and rebuild on my TBI. Supposedly this is going to give me better gas mileage and more horsepower. I bought my truck because it had a lot of horsepower to begin with. Unfortunately the previous owner as installed the re burner inappropriately. When the Racing store explained it to me I went from happy with my strong pickup truck to yeah my son's not borrowing this one to go on a date. It appears I'm running a throttle body and injectors with a Turbocharger. And now that I've seen how it's supposed to be installed instead of the way I purchased it. Once I go through a complete rebuild on the TBI & properly install the exhaust charged Toronado remixer. I will be able to see what kind of horsepower I really do have on my new four-wheel-drive. I was told my fuel injectors are just fine other than they are a little bit dirty and need to be cleaned. So I picked up the full rebuild kit and checking all of the warnings very carefully. As it appears I actually purchased a souped-up four-wheel drive and should expect both better fuel consumption which will increase my mileage and my horsepower well not costing me anymore in gas and maybe even less. It appears my Silverado is one step below a Vortec without having its balls cut. And to think I thought it had its horsepower because it has a rebuilt luck but my poor baby's been sick this whole time. I fixed her up three months ago and I had no clue she was souped-up I just needed a strong four-wheel drive.

If you want to add performance & stay with all ACdelco parts you can put your injector pod onto a 454 tbi body. This will double your cfm from 420 to around 880. Your bore is 1 5/8 & a 454 bore is 2 inches. You'll have instant throttle response. You'll gain noticeable power & also mpg. More air in always better. I did have an edelbrock intake bored out to fit the 2" port holes of the 454 tbi but you could simply add a tapered tbi spacer. I also added an injector pod spacer for better atomization of fuel. I had a stock 350 with this mod & it would roast my 35" tires. The only none stock part you would need is a plug adaptor for the map sensor. I got 20-22 mpg in my 93 1500 extra cab with 9 inches of lift & 35" tires.

Tip: prior to replacing the gaskets (paper based) rub them with chapstick liberally. This will prevent them from sticking when you remove them next time. PB Blaster also aids in gasket removal. Spray some on and wait a bit then scrape. Always a good idea to keep the TBI bores on the manifold covered until it's time to reconnect the TBI.

Jimmy, the way to properly check your injector spray pattern is simply done with a timing light, it’s the same for Chevy Ford or Chrysler TBI injection systems. All 2bbl TBI units are crossfeed designs, meaning for the Chevys/Chrysler’s the driver side injector supplies the passenger side of the engine cylinders 2 - 8 and the passenger side injector supplies the driver side driver side of the engine cylinders 1 - 7. For Fords it’d be passenger side cylinders 1 - 4 & driver side cylinders 5 - 8 with the same config of the opposite side injector feeding opposite sides of the engine as well. Then, simply place the timing light clamp on ANY cylinder spark plug wire on the passenger side of the engine to check the driver side injector and likewise ANY cylinder spark plug wire on the driver side to check the passenger side injector. Then you to point the timing light at the Venturi (under the injector) showing visibly the injector spray pattern on either injector as the spark plug is fired and shows dribbling, dripping, clogged or poor flowing injector spray pattern. Perhaps, you can do it to see it for yourself then again in a video to show others as well for diag purposes and more content for other automotive DIY’ers like yourself. It’s good to check TBI spray pattern anytime a ignition tune up is being done or if a cylinder misfire is suspected and spark is verified but the miss still persists. Personally on these older TBI units I check spray pattern at every ignition tuneup, cylinder miss diag, fuel system diag, O2 sensor diag, emissions diag specifically EVAP diag and prior to catalytic converter diag. This spray pattern check can surely tell you if your injectors are clogging, causing a lean/rich condition, if EVAP system if causing injectors to pull back fuel flow causing lean condition or rich condition that would affect the catalytic converters.

@midnight-xpress11364 жыл бұрын
For those wondering replacing injectors usually does two things. Like jimmy said they will help restore, restore being the key word, throttle response and some what fuel economy. I say somewhat because if you have leaky injectors that will cause poor fuel atomization and you go through more fuel, making a little less power. Hence the throttle response. Better fuel economy will be realized due to O2 sensors. These control your fuel trims. If you have a clogged injector or bad spray pattern, your fuel trims from what the ecu reads will either take away or add fuel to try and keep the fuel ratio right. But that only will be able to do so much. PS getting some arasol gasket remover spray, can go a long way to help getting stubborn paper or cork gaskets off.

Not once did you use a can of Carb Cleaner and a tooth brush. WD-40 doesn't work to remove old gasket material. Carb Cleaner does ! And you don't use a Razor blade scraper. Like you said, "It will dig into the aluminum". You use a 1 1/2 inch wide stiff Putty knife. And scrape off the excess material. And you should make sure, to get rid of ALL, the excess gasket material. As when you put on the new gasket. It may not seal properly, because of the uneven surface ! As long as you tighten each screw, so it is SNUG. You will be fine. DO NOT tighten the screws. As in Crank on them. You will strip out the threads. It's Aluminum remember ! You can tighten down the 3 mounting bolts to 20 Inch pounds. But if you use some Hi Tach gasket Sealer from Permatex. Just Snug them down evenly. And you won't get any vacuum leaks. Proper Atomized fuel, gives you a much better throttle response. Than shooting drops of fuel into the engine. And you will get better gas mileage. Over all, your video was very descriptive and had really good detail. You showed each step very well. And your narrative was pretty darn good too ! No blurriness or jumpiness. A very good video Jimmy !

Yes, pull the relay while it's running. And that was an open end wrench you showed, not box. A wrench with both box and open end is called a combination wrench. Fine thread fasteners are almost always lower torque. The wrench Jimmy used to brake torque with was a little larger than what you'd want to use going back together. Why? Because you can easily apply excessive torque with a larger wrench. The throttle body is made of a softer metal alloy and with steel fasteners, it would be fairly easy to over torque and actually pull the threads from the casting (that would suck). The same with the 3 mount bolts into the manifold. Snug and a light tug, that's it. Best to use 1/4 drive wrench going back together. One thing to keep in mind before you do this job is that the butterfly shaft in throttle body can wear and create a vacuum leak just like with a carburetor. You can easily test for this condition by spraying carb cleaner at the shaft with the engine idling. If there is a vacuum leak at the shaft the engine will slow down when it sucks in the carb cleaner. This is a common problem on older vehicles.

Now yes, I will admit that the TPI does seem to have a little more output. But if you ask me - this system is by far the best way to go. It has that good Rochester Quadrajet look to it. Maintains good for reliability. Not to mention, if you ever get stuck on the side of the road, you can throw a carburetor on this design and be on your Merry way.

Great video! I have a 94 Silverado 5.0, 384k original miles same engine. I recently thought I would spray some throttle body cleaner through the TBI. Well, it must've broke some crud loose and after that, it had a hesitation on the pedal. Thought maybe messed up a sensor, but no. So, I took apart the throttle body and did a deep clean. Bought the fuel pressure rebuild kit as I rebuilt the throttle body a few years ago. Spraying the throttle body while on the engine only does so much. After reinstalling, the hesitation has been cleared up. Not a difficult job to do at all. I too felt an increase in the throttle response! OH, I noticed you have an ANTI LOCK BRAKE light on. Mine failed several months ago. I disconnected wire for a while but went to the salvage yard and picked one up for $15. Problem solved! Gotta love working on your own stuff! Great sense of pride in your accomplishments.

Use a timing light in a dark garage to inspect injector pattern. Take off the fuel fittings before unbolting anything. The will both come out. Clean the old gasket with a good wire brush after soaking it with carb cleaner for about 15 minutes. Good job for a beginner though.

Great job. You will maybe see an increase in fuel economy. It is good practice to put some clean towels in the intake as soon as you remove anything. Your hot start with heat soak will improve as the injectors will not leak and make the hot start too rich.

***Don't use razor blades, or razor blade scrapers*** The TBI is aluminum, and you can do some serious damage. Use plastic razor blade scrapers (your auto store should have them). Once you get it apart, soak everything in a carb cleaner dip basket (again, your auto parts store will have it) for a couple hours. This will soften up everything. Using the scotch pad he used (grey color) is fine for the flat surfaces. Tooth brush, and a pipe cleaner brush will get the passages clean. I use anti-seize on all the screws to prevent galling and prevent galvanic corrosion. Use a very thin coat. Also, the O-rings just need to be "shiny" when you lube them.. he had too much here. He did a great job. It's a 1 beer rating on the 1 to 10 beer scale of difficulty.

Nice job Jimmy, I do not often comment on DYI home films, but I really enjoyed your narrative and your to the point explanations. I am working on a TBI system and did not remove the throttle body base as you did. I just took of the top. I had not worked on this type fuel system before and I will say your film was very helpful. And more importantly, I actually enjoyed it and watched the entire film. (that seldom happens) Thank-you!
@VigilanceTech2 жыл бұрын
did you ever just try and run some fuel injector cleaner in your gas tank? Also, when you're using a razor scraper like that, if you run it backwards over your windshield a few times to give the edge of the blade a slight curve upward making it much less likely to dig into the soft aluminum. I do this all the time to remove things like overspray, hardened pitch, or road tar from my car's paint finish

80's Ford guy mentioned using a timing light to check the spray pattern. You might be able to do the same thing with a LED flashlight, one that has two or three levels of brightness. I think the LEDs pulse quickly to reduce the brightness. Holding one under a water faucet totally changes the look of the water coming out because of the strobe effect. Now that I said this I'm going to try it tomorrow to see if I'm stupid or not. 😁

Im going to rebuild mine as a start of diagnosing a no pulse issue. I had been having some issues with my 5.7 tbi for a while not. It just hit me last night that my injectors are spraying almost full force. very spraying with no pulse operation as your rand new rebuild is doing. yesterday i took note on a cold start that it was almost like the engine was running rick. Sort of like tuning the carb on a small engine and the you increase the flow too much. then i remember that my injectors were spraying very loud with a good steady spray pattern instead of a pulse. this also explains the high fuel consumption. Im getting more fuel that is being used.

For all in the know...it's probably best to do a full Idle Valve reset after an overhaul like this. These TBIs get wack once they start running rich and dripping fuel so the computer compensates by opening up the Idle Air Valve to max open. Sometimes they get stuck open (buildup, etc.). Rebuild the TBI, clean the Idle Air Valve (they hardly go bad), replace the Throttle Position Sensor (They are super cheap) then perform the Idle Valve relearn procedure. Your truck will be purring like the day it left the lot. Folks forget about the Idle Air Valve relearn procedure and wonder why their truck still runs like crap still. Oh and there is also that annoying thing called a fuel filter. If you are working on TBI rebuild then you can sure bet you need to change the fuel filter also on any piece with high miles.
