As the title says I have no idea whats wrong. Its a 95 GSR OBD1. I removed the IAB, the EVAP is hooked up, no leaks. other than at the Throttle body which I intend to fix tomorrow. I sprayed carb cleaner around all gaskets and didn't hear the idle drop till I got to the Throttle body. So I tried to drive it thinking it was a fluke, and it cuts out when I try to put it under stress. I have no idea whats wront, I have NO CELS. Using my Stock TB. please help. Thanks

 

Are you saying that when you drive the car and begin to put a load on it, the car dies completely? Or does it just jerk for a second and go back to normal as soon as you take your foot off the pedal? What is it doing as it idles? Does your CEL come on when you start the car and then turn off like normal after as few seconds (just making sure your bulb isn't burnt out)?

 

Tps, or map they might be switched also.

 

Yeah the light comes on then turns off when I start it. It just dies completely when I try to pull off. and it idles fine. no fluctuating no nothing. I can move the car but I have to stay below 1/4 throttle. I feel like if I had the MAP and TPS mixed up it would throw a CEL

 

Exactly what I was thinking but he would def have a CEL if this was the case..

I can't explain why the CEL isn't on but what you are describing is very much like a TPS/MAP issue fucking your ignition and fuel up. Go unplug your MAP and TPS and switch them and see if it throws a CEL. If it doesn't then try to move the car again. Should only take 5 minutes

 

I forgot to mention if I move the throttle while the car is sitting it still cuts out after 1/4 throttle

 

So you can hold the throttle open and instead of revving up the motor dies? How does it idle? Does it idle smooth at cold idle and warm?

 

yeah. idles fine. fluctuates a bit when warm. im using the iacv that i got with the manifold. im thinking its obd2.

 

oh shit and i never checked to see if i tightened my iat.....

 

i can revv it to like 2500 to 3000 but thats it then it starts to choke out
