Oldsmobile 98 Engine Control Module (ECM) can fail

(10 reports)

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

Haven't had it checked yet. Problem just started last night. Service-Engine-Soon light came on. Then periodic stalling of the engine. The light would go off for about 10 minutes of driving then come on again. I drove for about 15 miles (in-town driving, not freeway). The engine only stalled about 4 times during that 15-mile drive. The stall seemed to happen when slowing down to stop at an intersection or would stall immediately after coming to a complete stop. In every case of a stall, the engine would easily start up again with the turn of the key in the ignition. -
