Is Your 1997 Grand Prix Running Rough? Get The Right Fix, The First Time.
If you’re dealing with a frustrating no-start condition, erratic engine behavior, a persistent Check Engine Light, or poor fuel economy in your 1997 Grand Prix, a failing Powertrain Control Module (PCM) is a very likely culprit. Over my 20+ years in the garage, I’ve seen firsthand how a faulty engine computer can turn a reliable GM vehicle into a source of constant headaches. It’s the brain of your engine and transmission, and when it fails, nothing works right. This isn’t just a part; it’s the solution to getting your car back to the dependable machine it was meant to be.

Expert Pro Tip: Check Your Connectors Before Installation
Before you even think about plugging in your new PCM, take a bright flashlight and carefully inspect the vehicle’s harness connectors. On these 25+ year-old cars, it’s incredibly common for the connector pins to get corroded (appearing green or white) or even become slightly bent. A poor connection can mimic the symptoms of a bad module or cause your new part to not function correctly. Use a small amount of electrical contact cleaner and a soft brush to gently clean the terminals for a solid, reliable connection. This simple five-minute check has saved my customers from hours of diagnostic frustration.
Easy Plug-and-Play Installation: Get Back on the Road Fast
You don’t need to be a master mechanic to install this part. With basic hand tools, you can have your Grand Prix running smoothly again in under an hour. On most of these GM models, the PCM is easily accessible in the engine bay, often located inside the air filter housing.
- Safety First: Disconnect the negative terminal from your car’s battery.
- Locate the Old PCM: Open the air filter box assembly to access the module.
- Disconnect the Harnesses: Carefully unclip the wiring harness connectors from the old module.
- Swap the Modules: Remove the old PCM and set the new, programmed module in its place.
- Reconnect Everything: Securely plug the wiring harnesses into your new PCM. You should hear a distinct click. Reassemble the air filter housing.
- Final Step: Reconnect the negative battery terminal. Your vehicle is now ready to start.
