Random idle acceleration (2000=4000rpms when should be idling) leading to surging of car. Started a few months ago with a check engine light. Dealer replaced transmission sensor, problem has not been solved. I have had car checked out at dealership, but the problem is random, and they have not duplicated it. Has been happeining randomly for last few months, at least a couple times every time the car is driven to work--23 miles one way. Must push the break as hard as possible to keep car from lunging when the problem occurs.
