Report: Stalling Due to Mass Air Flow or Crankshaft Position Sensor Failure
Buick Regal Problem
Engines Affected: 3.8L V6, 3.8L V6 Supercharged
Average Mileage: 155,533 mi (90,000 mi - 213,000 mi)
The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

Car stalling repeatedly, suddenly and without warning or sluggish performance. No DTC codes found with Actron Scan Tool. Had shop run tests, they recommended either MAF and/or CPS replacement. Replaced MAF myself, but stalling continued; then ran code scanner again, and popped P0336, stating pending CPS problem. Considered this definitive proof of cause of stalling. Scheduled CPS replacement.
