So far this is the strangest thing that has happened with the M. I took out the car about 2 blocks, parked and shut off the engine for about 5 minutes. As I drove off the car started hesitating real bad. It felt exactly as if I were giving it gas and then releasing off the accelerator quickly. It was jerking really bad. The car coasted fine if I didn't give it gas but the minute I gave it gas it would jerk. This entire time I was in 1st gear. I coasted about one block....then it just went away. The car pulled fine. It was raining pretty bad but I didn't go through any puddles....any insights?
