Hi, I've been searching in this forum for a thread that has something about the engine vibrating at stops and the Engine Check light turning on and off on it's own. I'm from Mexico and took the car to the dealer and told me that the code was a cilinder missfired but was not an active one, so they just ereased the code and that was it (no charge for it) but the car is still vibrating at idle sometimes. Does anyone has a clue about this? Thanks!
