Restore Your Vehicle’s Core Performance
Is your 1998 Buick Skylark, or another compatible GM vehicle, suffering from erratic engine behavior, poor fuel economy, or a persistent Check Engine Light? These are classic signs of a failing Powertrain Control Module (PCM), the central computer responsible for managing your engine and transmission. A faulty PCM can lead to a cascade of frustrating issues, from rough idling and stalling to incorrect transmission shifting and even a no-start condition. This replacement PCM, part number 9366314, is the definitive solution to restore your vehicle’s reliability and drivability.
This isn’t just a generic, off-the-shelf part. We take the guesswork out of the repair by programming the module specifically for your vehicle. Upon purchase, you will provide us with your Vehicle Identification Number (VIN). Our technicians then flash the module with the latest, most stable software updates directly from General Motors. This ensures that your vehicle benefits from all factory improvements for fuel mapping, emissions control, and transmission shift points, delivering performance that is often better than the original.

Expert Pro Tip
Before replacing your PCM, always verify your vehicle’s battery is fully charged and the battery terminals and main chassis grounds are clean and tight. Low voltage or a poor ground connection can mimic PCM failure symptoms. A simple check can save you time and ensure your new module functions correctly from the start.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough or unstable engine idle.
- ✔ Engine stalling or hesitation during acceleration.
- ✔ Harsh, delayed, or incorrect automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
The Importance of a Programmed 1998 Skylark PCM
In modern vehicles, the PCM is intricately linked to the entire vehicle’s electronics system. A replacement module must be correctly configured to communicate with the other computers, sensors, and the anti-theft system (PassLock/VATS). Our VIN-programming service handles this critical step for you. By matching the software to your exact VIN, we ensure seamless integration. While the module comes programmed, some vehicles may require a simple, on-vehicle security relearn procedure, which can typically be done without special tools. This process pairs the new PCM to your car’s existing anti-theft system. This commitment to vehicle-specific preparation makes our 1998 Skylark PCM a reliable and effective repair solution.
