1999 Pontiac Bonneville Q&A
1999 Pontiac Bonneville Question: Engine stalls intermittently.
Without symptoms will just quit running while driving. No indication to start for 5 to 10 minutes will start quickly and run perfect. Has no special time or event may run for 1/2 up to 2 days before stalling. Then after 5 to 10 min. will start and run great. Had some idle problems today tho. Does not show a code running or when stalled. Replaced fuel pump and ignition module to no avail. Full of gas no over heating. - Sorensond

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.
The crankshaft position sensor may fail causing the engine to stall intermittently, the Check Engine Light may or may not illuminate.
