Verified

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 would shut off randomly, at first only after it had been running for a while, but it got worse and would stall any time/at least twice per day. Replace mass air flow sensor 3 days ago, hasn't stalled since.

    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.

    Car dies varies times no special speed or RPM Finally security light comes on, pointing to the key and/or ignition switch. Traded to wife's original, seldom used key After the three minutes, car started drove the 1800 miles home with no more problems. Buick dealership wanted to replace crank sensor at $200. Maybe a good guess generally. The key is just another thing to check. Book also suggested just clean the key. At the 240000 on the 7000 mile trip the 3.8 did not require any added oil and still gets from 29 to 31 MPG at freeway speeds. Finding it hard to replace with a new car.
