Is Your Skylark or GM Vehicle Running Poorly?
If you’re dealing with a persistent check engine light, rough idling, stalling, or unpredictable engine performance in your 1997-1998 Buick Skylark, the Powertrain Control Module (PCM) is often the culprit. As a technician with over 20 years of experience, I’ve seen these exact issues countless times. The PCM is the brain of your engine, and when it fails, it can cause a cascade of frustrating problems that can be difficult to diagnose. This isn’t just a part; it’s the central command for your vehicle’s performance and reliability.
The Direct Solution: A VIN-Programmed PCM
Forget expensive dealership visits and the hassle of finding a local shop with the right programming equipment. We provide a straightforward solution. This PCM is meticulously tested and programmed with the latest official GM software updates, tailored specifically to your vehicle’s Vehicle Identification Number (VIN). This ensures perfect communication between the module and your car’s systems, restoring it to factory specifications.
From the Shop Floor: A Tale of a Tricky Misfire
“A customer’s 1998 Grand Am with the 2.4L engine came in last week with a persistent P0302 code (Cylinder 2 Misfire). They had already replaced the spark plug, wire, and ignition coil, but the misfire wouldn’t go away. Instead of just throwing more parts at it, we hooked up our scope to the cylinder 2 fuel injector. We found the pulse signal from the PCM was weak and erratic compared to the other cylinders. This confirmed our suspicion: the injector driver circuit inside the original PCM had failed—a common issue on these units. We installed one of our VIN-programmed PCMs, and the car ran perfectly smooth, instantly. It’s a classic case where the problem isn’t the component, but the computer controlling it.”
Common Symptoms of a Failing PCM:
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or cutting out while driving
- ✔ Rough or erratic idling
- ✔ Noticeable decrease in fuel economy
- ✔ Failure to pass emissions tests
- ✔ Harsh or incorrect automatic transmission shifting
- ✔ No-start condition where the engine cranks but won’t fire

Plug-and-Play Installation: No Dealer Visit Required
You can install this module yourself with basic hand tools. Here’s a general guide:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes for the system to fully discharge.
- Locate the PCM: On most of these vehicles (like the Cavalier, Sunfire, and S10), the PCM is located in the engine bay, often on the driver’s or passenger’s side firewall or inner fender. On others (like the Grand Am or Malibu), it may be under the dash. Consult a repair manual for your specific model’s location.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old PCM. Inspect the pins and connectors for any corrosion or damage. Clean them with electronics contact cleaner if necessary for a solid connection.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed PCM into place.
- Reconnect Everything: Firmly re-attach the wiring harness connectors until they click into place. Reconnect the negative battery terminal.
- Final Step: Your vehicle may need to complete a security relearn procedure, which can typically be done without special tools by cycling the key. Instructions are readily available online for your specific model.
