Idle problems

I have a 99 LT and recently the idle is not working properly. At cold starts the engine tends to die. As the engine warms the idle is normal RPM, around 900. When the engine is at operating temp, the idle is at about 1250 RPM. I have a new air filter and my mechanic, from a phone call description from me, says it is the "stepper motor" also called the idle control mod i think. Any one?

Re: Idle problems

same problem on my '01. throttle position sensor needed adjusted. you will need a gs-911 if this is your problem.

Re: Idle problems

I looked and I think the stepper motor is the throttle valve actuater in the repair manual. could the throttle position sensor be called something else?

gs-911 is similar to the moditec that the garage uses, i think i would start by adjusting the tps if you can borrow a gs-911. of course the dealer can fix this if you can not

Re: Idle problems

Thank you edmann for the information. Thanks for making me awarwe that there is an adjustment that may possibly fix the problem I wasn't aware before.

Re: Idle problems

there is a write up on this procedure, look up tps adjustment. its not difficult, a bit time consuming though
