Restore Peak Performance to Your GM Vehicle
Is your Oldsmobile Achieva, Chevy S10, Pontiac Grand Am, or other compatible GM vehicle suffering from frustrating and unpredictable engine problems? Issues like a persistent Check Engine Light, rough idling, stalling, poor fuel economy, or a complete no-start condition often point to a failing Powertrain Control Module (PCM). The PCM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting. When it fails, the entire system’s performance and reliability are compromised.
This replacement Powertrain Control Module, service number 16228016, is the definitive solution to get your vehicle back on the road and running as it should. We eliminate the guesswork and costly dealership visits by providing a module that is professionally programmed with the latest official GM software updates. This ensures optimal performance, fuel efficiency, and emissions compliance, tailored specifically to your car or truck.

Expert Pro Tip
Before you replace your PCM, take a moment to inspect and clean the main engine-to-chassis ground straps and the battery terminals. A poor ground connection can cause erratic voltage signals that mimic the symptoms of a failed computer. Verifying these connections first can save you time and money.
Common Symptoms of a Failing PCM
If you’re experiencing any of the following issues, a faulty engine computer could be the culprit. Replacing your module with this pre-programmed unit can resolve these problems:
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Vehicle fails to start or starts intermittently
- ✔ Stalling or rough running, especially when idling
- ✔ Noticeable decrease in fuel mileage
- ✔ Harsh or erratic automatic transmission shifting

- ✔ Unexplained engine hesitation or power loss
Why Choose Our Programmed 1997-1998 Achieva PCM?
Our process is designed for simplicity and effectiveness. Unlike a generic, off-the-shelf part, this module is not just a piece of hardware; it’s a complete solution. When you place your order, you provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians then use this VIN to load the exact, correct GM calibration file onto the module. This critical step ensures that the computer communicates flawlessly with your vehicle’s specific engine, transmission, and options package. This is the same procedure a dealership performs, but without the high cost and inconvenience.
