335i Engine shakes/shudders at high RPM under acceleration

bmwdrvr2 · 02-05-2011, 01:51 PM

When under hard acceleration, and when in high RPM's the engine will start shaking, and shuddering. It will continue to do so only if I press the throttle, if I coast the car is fine. It will continue like this unless I restart the car, then it drives fine again. If I drive it easy it will run fine, it only happens under hard acceleration. I have been to the Dealership three time to fix the problem, twice they reprogramed the pump, once they switched two coils around. Has anyone had the same problem and if so what was done to fix the car?

They need to REPLACE the pump.
Also, switching coils around? What kind of dealer is that? If you were out of warranty they would have replaced the coils if they thought something was wrong with them.

They switch coils around to diagnose if the coil is the problem for bad spark. If bad spark follows the coil, then the coil is defective. Common practice.

Sure for an indy, not a dealer.
