Hello, I am not sure if this is a problem or not, but I have stalled the car on a few occasions and when I try to start it the engine churns and churns, albeit very bumpily as though the timing was out or something, then she will suddenly fire and run normally. Also more recently I have experienced the issue from a cold start up, again very bumpy turn over, it feels like when you are driving on the point of stall and the car shudders. Very odd. Any ideas anyone??
