1990 Oldsmobile 98 Q&A
1990 Oldsmobile 98 Question: Why does my olds 98 stall sometimes and then immediately restart?
The condition occurs most often after idling for a few minutes such as in traffic or waiting at a store. Sometimes just driving it will stall or start running rough. Without exception turning the key off and immediately restarting it clears the problem. There have not been any codes set and have not been able to duplicate when connected to a diagnostic computer. Any ideas? - mmengon
One of the most common cases for intermittent stalling on your 1990 Oldsmobile would be the crankshaft position sensor. Another likely cause would be the mass airflow sensor. - Jim Taddei
