Same thing happened to me. I was able to nurse it along for 2yrs and just use the car for under 13mile commuting. The vibration and heat would create a gap in the pins, or prongs to some, in the crank sensor PLUG. Same thing would happen to me, stutter, buck, miss, bog, and eventually throw a code and stop the motor. Stefan just soldered a new plug to the wires, shrink tubed it, and viola, good runnin' motor. You may be able to recreate the problem by doing this: Start car in neutral, have some one rev it at a constant 3K (it may help to have the engine up to temp if heat is part of this equation). Locate Crank Angle Sensor pigtail/harness/plug and tug gently>>>Firmly on it and see if there is a drop in the RPMs(stutter/buck/miss/bog). If this happens then check/replace the plug. Hope this helps. :up: Kevin
