The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

2001 Pontiac Bonneville Reviews

This is my second Bonni and I just love it. I have had only minor problems from it and with good maintenance, it runs great! Right now it has 160,000 miles and still running strong.
