Expert Insight: As a technician, I’ve seen countless hours and dollars wasted chasing intermittent electrical gremlins. A common culprit is the ECM. The internal circuits can develop tiny fractures that cause issues only when the engine is hot, leading to stalls that mysteriously disappear after the car cools down. Instead of swapping sensor after sensor, addressing the core problem with a properly programmed 2009-2010 Pontiac Wave ECM is the most efficient and permanent repair.
