I'm sure this question is covered somewhere in the forums, but I couldn't find it.

When my wife's Durango is cold the idle jumps up and down on it's own. I cleaned the TB and it was great for a couple hundred miles and started doing it again. I don't receive the check engine light or anything and it only does it when cold. I am going to change the TPS, though I am not getting a code.

Any thoughts out there?
thanks,

The TPS usually doesn't throw a code so you're on the right track...

 

Thanks for the reply, I will let you guys know what the results are. Tues. is my next day off so that's when I'll do it.
