Low rev for some reason
Hey my 86 TA is having a hard time going over 2200RPM, and acceleration is really slow compared to before. It hesitates when I hit the gas, takes a little while sometimes to start. Runs good when cold/in cold weather. Any ideas? (maybe fuel pump?) Thanks!
PS also I have a check engine light when I'm going under about 50km/h, and it goes away after I'm going faster than that.

Yeah it's a TPI.. is there a way I can pull codes without a scan tool? I have access to a Tech 2 at my school but I won't be able to get in there until Monday, wanna get it looked after before then.. I fixed the TPS and the check engine light is gone now but I still have that hesitation

autozone does it for free but if the ses light is gone then they wont get any codes... my guess is youre a/f ratio is off
