Is Your 1996 GM Vehicle Running Rough, Stalling, or Refusing to Start?
As a mechanic with over two decades of experience under the hood, I’ve seen countless drivers frustrated by mysterious engine problems. You might be dealing with a persistent Check Engine Light, erratic idling, poor fuel economy, or a car that just won’t cooperate. Often, the culprit isn’t a dozen different sensors, but the one component that controls them all: the Powertrain Control Module (PCM).
A Real-World Scenario from My Shop
“Just last month, a 1996 Sunfireโwhich uses this exact same computerโwas towed in. The owner had replaced the plugs, wires, and even the fuel pump, but it still had a nasty intermittent stall when it got hot. After confirming fuel and spark were good, we focused on the PCM. A quick tap test on the old unit made the engine stumble, confirming an internal failure. We installed a pre-programmed PCM like this one, and the car was running smoothly within 30 minutes. It’s a common failure point on these mid-90s GM vehicles that often gets misdiagnosed.”
