Idle problems again..

T seams that I can't ever get my idle to drop.. I come up to a stop sign and throw it in neutral and my idle stays al like 1500rpm it takes anyware from 30 seconds to like two miniatures to drop. I'm stumped and do know ware to even start..

Re: Idle problems again..

have you checked the idle screw on the TB or the TPS? Usually the TPS goes bad

Trojan,
Should u replace the tps even if the voltage checks good? I have a 92 gt with the same idle problem. Still can't figure it out. I am pulling 17-18 of vac so I don't think I have a vac leak

If the voltage scales up and down smoothly when you open and close the throttle with the meter hooked up, then it should be ok.


Read the articles about idle issues and how to cure them in the Useful Info thread.
Also you need to follow the procedure in your Chiltons manual to reset the idle.
Do not just crank the idle screw up or down.
