Is Your 1997 GM Vehicle Running Rough?
If you’re dealing with a frustrating check engine light, unpredictable stalling, poor fuel economy, or a car that just won’t start, the problem often points directly to a failing Powertrain Control Module (PCM). As a technician with over two decades of experience under the hood, I’ve seen how a faulty PCM can turn a reliable car into a source of constant headaches. It’s the brain of your engine and transmission, and when it starts to fail, the symptoms can be confusing and widespread.
This isn’t just a replacement part; it’s a direct solution. We are providing a Powertrain Control Module, service part number 16217058 (also replaces 16218070), that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module communicates perfectly with your car’s systems right out of the box.
Real-World Diagnosis: From the Shop Floor
“A customer’s 1997 Pontiac Grand Prix came in last week with these exact symptoms: intermittent stalling at red lights and a persistent P0300 random misfire code that mechanics kept chasing by replacing plugs and wires. After checking all the basics, my scanner pointed to an internal PCM fault. The original module’s internal processors, after 25+ years of heat cycles, were failing. We installed one of our VIN-programmed modules, and the car ran perfectly. The customer was thrilled to have their reliable daily driver back without the guesswork.”

Simple Plug-and-Play Installation Guide
You can do this right in your driveway. The PCM on these GM models is typically located in the engine bay, often inside the air filter box for protection.
- Safety First: Disconnect the negative terminal from your car’s battery and wait 10-15 minutes for the system to fully discharge.
- Locate the PCM: Open the air filter housing. The PCM is the metal box with several large multi-pin electrical connectors.
- Disconnect Connectors: Carefully unclip and remove the electrical connectors from the old module. Inspect the pins on the vehicle’s harness for any green corrosion or bent pins. Clean them with a dedicated electronics cleaner if necessary.
- Swap the Modules: Remove the old PCM from its mounting bracket or housing and set the new, programmed module in its place.
- Reconnect Everything: Firmly plug the electrical connectors into the new PCM. You should hear or feel a click. Reassemble the air filter housing.
- Final Step: Reconnect the negative battery terminal. The vehicle is now ready to start.
