Thanks for the suggestion... I have noticed that after warming up, my idle speed is pretty much back to normal. I have also noticed that this has only occurred since the weather got cold??? Hmmmmm.Originally posted by Djnrg:
Hmm....could be your throttle position sensor on the Throttle Bodies. If it has gone, it can have this effect. I actually modified it to trick the computer into thinking the TB's are open more than they are, and to make it idle higher, for a faster launch. Then again, it could be the idle control motor, which would be a pain in the ass if that went. Try obtaining the fault codes in your on board computer. That might give you some insight on the problem.
