Hi there! Thats my first post but Ive read tons of topics over here and havent found exact problem as mine. It happens when driving back from work, Ive kickdown the pedal gas and suddenly loosen it cause of situation on the road, and then all the strange things begin. When I stop the car on the traffic lights I can feel the engine(?) shaking, The car has less power feels like engine choking or so... but when i restart(turn off the car and start again) everything goes away, accelerate smooth, no car shaking until I try to kickdown it again. Regards
