after driving awhile ( the time doesn't seem to matter) the electronic throttle control light will come on followed by the electronic stability program light. I have taken to a dodge dealer and they replaced map sensor, but this has not helped.

Hi crg3400,


Thank you for the donation.

What was the trouble code retrieved?
Did you refer back to the dealer which performed the job?
