I have a 91 trans am gta with a tpi 350 it falls on it face when accelerating its realy sluggues hot summer day it dont run go at all does anyone know what is wrong or have suggestgens?

I now have a code 32 my book says EGR,EVAV
Thanks for the help any more suggestgens will help

 

have you tried trouble shooting? tune up good? any codes?

 

As Ed advised, verify the ignition components, air filter, fuel pressure (pump and filter), and clean teh throttle body - including the idle air control and its air passages. Set the minimum air position and check the TPS voltage to make sure it is within the specification. A '91 should have a non-adjustable TPS, so the TPS voltage should be at 1.0VDC or less in the closed throttle position.

Once that is done, you hesitation should be minimal, or you will at least have verified the necessary systems are working correctly so that you can perform some serious troubleshooting.

 

i got an issue. My GTA was going fine, but then all of a sudden, i could accelerate fine til I tried WOT, and it just lost all power. In park, i can rev it up, but when i git to around 4000 RPM, it just starts to bog and lose power, i let off and it goes back to normal idle. Now mind you it sat up for about 5-6 years, i replaced the fuel pump, sending unit, had a fuel system cleaned, it has been running like a top like i never parked it.
All this happened when i got to take my daughter out in it for the 1st time . At least she got to git slapped back after a hard 2nd gear scratch.

i got no check engine light on so dont know what to look for. Any help would be greatly appreciated.

Thanks.

 

sounds like a vaccuum leak to me. Or a weak fuel pump

 

give it a full tune up and new ignition coil

 

Check your injectors. I had three bad ones and it would bog around 4000 in park.

 

well i got out this morning and started it up, and i could rev it past 4 grand with no issues. i dont know if i have to let it get to operating temp. or what. i checked for codes this morning and nothing.

How would i check the injectors?

 

i just got home, and started the car with no problem, and ran it to operating temp. i got the car up to 4000 rpm and it didnt fall on its face. still no codes or nothing, i dont know what to do. this has me so crazy.

crazy thing is, i didnt do anything to the car. gonna take it out tonight and see what happens.
