My 2006 hemi after about a minute warming up all of a sudden revs up and comes back to normal warming up Idle .if I try to drive off before it does it it cuts off instead of reving up.stop,restart and drives like normal.dealer has no idea so I thought i would see if anyone had this problem before.

 

What model car is it?
If it is a Chrysler 300 and no one here has any ideas, try over at, Chrysler 300C Forum: 300C & SRT8 Forums - Powered by vBulletin
Model specific forums can be a great resource, because they usually have had someone with the same problem before, or can at least help you diagnose it.

I joined there about the same time I joined here, because having such large groups of people gathered together like this can usually help you diagnose any problems.
Oh, and please if you find the solution, please post what it was, so that others in the future who may have the same issue can find it.

This one has the advantage that it is the official Chrysler forum, and if a lot of people are reporting that their wheels are falling off when they put the car in park with a specific model. Chrysler already has a lot of details about the issue from here and can take action to resolve it.

 

Odd, I just saw that this is an old post, but it was in the new post listing.
