Hello everyone. New to the forum and i am talking about the wifes car. While driving yesterday I noticed that her car had a decent amount of engine shake while in gear. She drives the car like a grandma so i figured i would run it a little harder to blow some carbon out of it. Next stop light i put the car in 1st in auto stick mode and gave it 3/4 throttle from a launch...at 3000 rpm the engine felt like it hit rev limit and a massive cloud of smoke out the back....i mean massive cloud. No engine lights came on. Took the car to the dealership right after. Anyone else have this happen to them?
