I was driving home the other day and hit a couple moderate bumbs. All of a sudden I had a loss of power and trouble accelerating. It was fine if I accelerated very slowly but the engine still sounded like it wanted to cut out. Check engine light never came on the first day but I noticed that there was a strong sent of gas coming out of the tale pipes. The next day I started it up and the trac control and check engine light came on. Has anyone else had this problem?
