This is getting worse, to the point I am afraid to drive my car. While driving I can feel the car slowly accelerating, feels like it has more power. I will go to stop and press the brake, car will stop but engine will run at full speed. I have to shift it in to park and take my feet off all pedals, then it returns to normal. I have had several very close calls so it’s only a matter of time before it causes an accident. I have had it in the shop twice and they say they can not find anything wrong. A friend suggested it could be a faulty throttle position switch? Anyone have any idea or what I could tell the dealer to look for?
