Restore Peak Performance to Your GM Vehicle
Is your Oldsmobile Achieva, Chevy S10, Pontiac Grand Am, or other GM vehicle suffering from frustrating and unpredictable engine problems? Issues like a persistent Check Engine Light, rough idling, stalling, or poor fuel economy often point to a failing Powertrain Control Module (PCM). The PCM is the brain of your vehicle’s engine, and when it malfunctions, it can cause a cascade of performance issues. This replacement PCM, part number 16245305, is the definitive solution to get your vehicle running smoothly and reliably again.
Unlike a generic part from a salvage yard, this module is not just a replacement; it’s a complete restoration of your vehicle’s engine management system. We professionally program the module with the latest GM-certified software updates specifically for your vehicle’s unique Vehicle Identification Number (VIN). This critical step ensures perfect compatibility, optimal performance, and corrects many of the original factory software bugs that may have developed over the years. By providing your VIN at checkout, you receive a unit that is ready for installation, saving you a costly trip to the dealership for programming.
From the Diagnostic Bay
I once had a 1998 Chevy S10 with the 2.2L engine come into the shop. The owner had spent hundreds of dollars replacing the ignition coil, spark plugs, and even the fuel pump trying to solve an intermittent stalling issue. The truck would just die at stoplights with no warning. After checking all the new parts, which were working fine, I hooked up my professional scan tool. I noticed the PCM was intermittently dropping communication. On a hunch, I checked the driver circuit for the ignition control module inside the PCM. Sure enough, it was failing under heat. We installed a VIN-programmed PCM, performed the security relearn, and the truck ran perfectly. It’s a classic case of symptoms pointing to multiple parts, but the root cause being the central computer itself.
Common Symptoms of a Failing PCM
If your vehicle is exhibiting any of the following signs, a faulty engine computer may be the culprit. A replacement 1997-1998 Achieva PCM can resolve these issues and restore your vehicle’s dependability.
- ✔ Persistent Check Engine Light (CEL) illuminated on your dash.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Rough or erratic idling.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Failed emissions testing due to incorrect fuel/air mixture.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Communication errors when using an OBD-II scan tool.
Why Choose a VIN-Programmed Module?
In modern vehicles, the PCM is tied to the specific options and security system of the car it came from. Simply swapping a used module will almost always result in a no-start condition. Our process eliminates this problem. We take your vehicle’s VIN and flash this module with the exact software it needs. This ensures all components, from the engine and transmission to the anti-theft system, communicate correctly. This is the most reliable and efficient way to replace your PCM.
After installation, a simple security relearn procedure may be required to sync the new module with your vehicle’s anti-theft system. This procedure is straightforward and can be performed by you at home in about 30 minutes with no special tools required. We include clear instructions to guide you through the process.

Frequently Asked Questions
Do I need to have this PCM programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready for installation and the security relearn procedure.
What is a security relearn procedure?
It’s a simple process that syncs the new PCM to your vehicle’s existing anti-theft system and keys. It typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this sequence three times. We provide full, easy-to-follow instructions.
Is this part difficult to install?
For most of the listed vehicles, the PCM is located in an accessible area in the engine bay or under the dash. Installation typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. Basic hand tools are all that’s required.
Will this fix my car’s problems for sure?
If your vehicle’s issues have been correctly diagnosed as a faulty PCM, then this part is the solution. It will resolve all problems directly caused by the computer. However, it will not fix issues related to other failing mechanical or electrical parts, so proper diagnosis is key.
What information do you need from me?
We need your 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct, updated software for your specific vehicle configuration, ensuring a perfect match.
