very rarely this happens to my car. When I start the car, the engine races up real high and then slowly comes back down to normal. It usually only takes it about ten seconds to return to normal idle. If I put the car in gear while it's doing its high rev thing, the car lunges forward and usually dies. Because of this I usually just let it rev high for the few seconds, wait for it to calm down and return to normal. Does anyone have any idea what is wrong here? It only does this about once every two or three months. I am so confused on this one.
