High RPMs at Start
I'm sorry I have looked through all the posts I can. I have a 04 Durango 5.7 hemi that when I start the RPMs jump up to 2000. They almost immediately drop back to 600. I know this has to be high...right? So I'm thinking that the throttle body is going bad but I'm not sure. I quess if anyone what would cause this I'm all ears.
