Customer: replied 24 days ago.
there is couple of warning light on the dash, I don't know which one could be related to it
Expert:  Michael Warfield replied 24 days ago.

Ok, this is a common issue with either the throttle position sensor or a faulty electronic throttle plate. Usually a warning that says ASR or ESP accompanied with a "check engine" light would be the symptom. I would suggest you leave the key in the "on" position with the engine off for 5 minutes to see if the problem is fixed. If this reset procedure on the throttle plate/motor does not work, it may have to be replaced after the fault codes are read.
