Is Your Skylark or GM Vehicle Running Rough?
If you’re dealing with a persistent check engine light, unpredictable stalling, poor fuel mileage, or harsh transmission shifting in your late-90s GM vehicle, the Powertrain Control Module (PCM) is often the culprit. Over my 20+ years in the shop, I’ve seen countless vehicles from this era, like the Skylark, Grand Am, and S10, develop frustrating electronic issues that trace back to a failing computer. The original PCMs can suffer from internal component failure due to age, heat cycles, and vibration, leading to symptoms that can be a real headache to diagnose.
The Right Solution, Programmed and Ready to Install
This isn’t just a replacement part; it’s a complete solution. We are providing a dependable Powertrain Control Module, a direct replacement for service number 16228016. The critical difference is our service: before this module ships, we will program it specifically to your vehicle’s VIN. This process loads the latest, most stable software updates from GM, ensuring the PCM communicates perfectly with your engine, transmission, and all related sensors. This eliminates the need for an expensive trip to the dealership for programming.
Expert Pro Tip: Check Your Connectors First!
Before you replace your PCM, take a moment to inspect the large electrical connectors that plug into the module. On these vehicles, especially those where the PCM is mounted in the engine bay (like the S10 or Cavalier), the terminals can get corroded from moisture. A bit of green or white crust can cause intermittent signal loss that perfectly mimics a bad PCM. Disconnect the battery, unplug the connectors, and clean them with a dedicated electronics cleaner and a small brush. It’s a 10-minute check that has saved my customers hundreds of dollars in unnecessary parts.

Simple Installation for the DIYer
Replacing the PCM is a straightforward job you can do in your own driveway. While the exact location varies slightly by model, the process is generally the same.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the PCM: On the 1997-1998 Skylark, Achieva, and Grand Am, it’s typically found under the dash. On models like the S10, Cavalier, and Sunfire, it’s usually mounted in the engine compartment on the passenger side.
- Disconnect and Remove: Carefully unplug the electrical harness connectors. They have locking tabs that need to be released. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed PCM into place. Securely reconnect the electrical harnesses, ensuring they click into place.
- Reconnect Power: Reattach the negative battery terminal. The vehicle may need to run for a few minutes to complete its internal relearn processes.
