The dealer diagnosed my 2002 buick Park Ave. with code P0336 (faulty crank position sensor). They replaced that part. Did not fix the problem. I still have a "service eng. light" and an intermittent erratic tach. and a sudden slight "jerk" or stutter of the engine. The dealer wants more time with the car, I said no, and picked up my car with this problem still at hand. Any help out there?

According to the service manual there are two crank shaft position sensors on your 02 Park Ave and both sensors are part of the Ignition Control (IC) module. Do you know if the dealer replaced on sensor, both or the module?
