Is Your 1996 GM Vehicle Running Rough?
If your 1996 Buick Skylark, Regal, Lumina, or another compatible GM model is experiencing perplexing issues like stalling, erratic shifting, a persistent check engine light, or a no-start condition, the root cause is often a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM is responsible for managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it begins to fail, it can create a cascade of problems that are frustrating and difficult to diagnose.
This listing is for a direct replacement PCM, part number 16211539, which is fully compatible with service numbers 88963800 and 16231853. We take the guesswork out of the repair by programming the module specifically for your vehicle using your VIN. This ensures that all factory settings, including those for your specific engine, transmission, and options, are correctly loaded for a seamless installation.

Expert Pro Tip
Before replacing your PCM, always perform a thorough check of the vehicle’s battery, charging system, and all main power and ground connections. On these mid-90s GM vehicles, a corroded ground wire or a weak battery can cause voltage fluctuations that mimic the symptoms of a failing computer. A few minutes with a multimeter can save you from replacing a part that isn’t faulty. Check the main ground straps from the engine to the chassis and the negative battery cable connection points for any signs of corrosion or looseness.
