I've been working on my 89 trans am 5.7. Changed almost all the sensors, except the throttle position, which might contribute to my check engine light flashing once the electric fan turns on and the idle decreases. I'm at a loss as to why the idle decreases when the fan turns on.

Me and my brother have been trying to get his 85 vette to behave and run right. We’ve been chasing sensors and connection issues for over a year. I’m no stranger to older EFI stuff, or principles of engine management in general. Diagnosing these engines is HARD.

Sir, I just stumbled on to your channel, and I have to say do a great job in explaining everything. Your engine bay is what I'm striving for. I have a 1991 Chevy Camaro Z38 that I pick up from my Dad. This car was sitting for at least 8 years, and I'm starting to rebuild it. The body is in great shape, but everything else needs work. I will be reviewing all of your content.

Saw ya peel out at the gateway show today lmao!

Cool man I got formula 1987 Pontiac firebird...

Now, what kind of process are you looking at Mechanic wise? If you get a fuel leak due to that fuel pressure regulator going bad in let’s say a C4 Corvette?

Forgot the fan switch sensor in passenger side

perfekt thank you

Great video. One question. My 1985 5.7 L98 engine has these EGR small tubes on the runners on the drivers side and that passenger side . Does exhaust gas come up from the exhaust from BOTH banks ?

Just got rid of a monte carlo super sport with the same motor. It had good power, but too many fuel issues for me to keep it. It started running funny after about 2 weeks.

Poor camera skills great car

Beautifully done….

Hood insulation Protection for the Hood Paint 🎨

Awesome I did the same thing

Thank you !!!

Thats the nicest and cleanest L98 ive ever seen 🤩

This is great! Liked and subbed.

Loved those idea's. I have my fans always running with the switch. I want to do the trans cooler and tpi the same. My 88 GTA hate hot weather. I have a long,slow up hill driveway that runs my cars temp up. Thanks for the extra great ideas. The intake doesn't need to be water cooled when its sucking air that's cooler than the water circulating the engine. Cooler air fuel mixture makes for hotter 🔥. Much appreciated. Nice ride.

Nothing half Ass,Fantastic!

Any consideration for the First Performance Intake?

When the computer advances the timing, how does it physically do it inside the distributor? Do those little triangles on the outer ring move?

Wow now that’s a good vid on how the tpi ever work thank you so much !!!

That's way more in depth than I originally anticipated. Good job.

Where can we find that turn signal assembly?

Awesome video thanks for spending the time .

Great video, I am researching putting a TPI on my 383 in a Chevelle...I would need an aftermarket control unit...any advice?

THANKS FOR THE INFO, it's really appreciated. Reading and researching can only get ya so far. If trying to learn, this is the next best thing...

Thankyou!! I have so many more questions though

Nice car love the red

Hey Rick I’ve got an 87 IROC Z L98. Engine runs beautifully when cold but then after a couple minutes of driving and warming up it starts to stumble idle roughly, also feels like there’s a lack of power. Has new fuel pump, fuel filter and oxygen sensor. No check engine light. All injectors ohm out at 16 ohms when warmed up. Any ideas what it could be?

Forgot about MASS air flow sensor

Where in the Hell did you come from,WOW!,amazing to find someone who is good at telling us how to works,I have a 91 vette 350 and now I understand much more,Thanks very much,now you made me have to detail my engine compartment,cool

Sup Kato....Man she sure has come a long way from the streets of Abilene. Hope all is well Brother

Thanks for the info!! i recently got a 87 vette with the TPI 350. I know nothing about them so i am doing some research. Does anyone make a code reader for these?

Videos like this are priceless. You explained with technical detail how this engine management system works and provided visual aid. I should have to pay for this. Guess its car porn.

This engine confuses the hell outta me. I have a 305 with the t5, and the lines, wires and all that is so overwhelming. Not to mention the smogpump and all that garbage.

Nice work. A lot of prep to have that much red.

Sorry, but TPI was not way ahead of its time. GM went to Bosch for the electronic fuel injection part. It has standard (for the time) Bosch fuel injectors, and everything else is Bosch, or Bosch-compatible. The Tuned Port part is the intake manifold itself. GM power train engineers designed it for low-end torque, which is the reason for the very long intake runners. The fact is, ALL all engines have 'tuned ports'. Chevy marketing guys just chose to use that as a catchy name. This system was a huge leap forward for GM, but was nothing special in the broader world of EFI.

Hi, and thanks for the video. Original owner of an 86 IROC and I'm ready to go to a 383 myself. Would be very interested to learn some of the details of yours. Specifically, compression ratio, camshaft, injector size, and whether you had prom custom burnt for it and who did it for you if so thanks

Hi Rick, I restored my 1987 GTA and want more horsepower than the stock 5.7 liter. I have a 383 stroker with a Corvette +2 cam that should work well with my TPI. Question is, who did you trust to do your chip programming for your 383? Thanks, Greg

Hey Rick, I have the same set up and I’m having an idle problem. Wondering if you could help?

Why are the injectors only 24lb? Everything I read & researched, 30lb injectors make the most power. How’s yours run in the 1/4 or do you have any dyno numbers? Not trying to sound negative, your car is the bomb! I’m just curious cause I’m building the same thing.

Well done keeping a Third Gen. tpi engine bay clean! It's nearly impossible to do. Great summary and a must-watch for everyone with a tpi system!

BROTHER!!!! Man imagine me going to TH-camU and stumblin' on to your page!!! Know this car well!!! HMU MAAAAAAAAN

Woww that’s incredible! What a beauty!! Did u make custom parts or did u order?

i have a 87 gta 350 thanks for the info man.

by far the best strait forward information , you my sir are the man.

Can I get some good horsepower on my 350 with this
