Is Your 1997 Cutlass Running Rough, Stalling, or Showing a Check Engine Light?
If you’re dealing with frustrating engine problems like erratic idling, poor fuel mileage, shifting issues, or a dreaded no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. In my 20+ years as a technician, I’ve seen how a faulty PCM can turn a reliable GM vehicle into a source of constant headaches. The PCM is the brain of your engine, and when it fails, it can cause a cascade of confusing symptoms that are difficult to diagnose. This isn’t just an inconvenience; it’s a critical failure that affects your car’s performance and safety.

- ✔ No Dealer Visit Required: Save hundreds of dollars and the hassle of towing your car to a dealership for programming.
Expert Pro Tip: Check Your Connectors First!
Before you even think about swapping the module, take a close look at the electrical harness connectors that plug into the PCM. Over the decades, these can accumulate green or white corrosion on the pins, causing intermittent signal loss that perfectly mimics a failed computer. I’ve seen this on countless GM W-body cars from this era. Use a small pick and a quality electronics cleaner to gently scrub the pins on the harness side. A solid connection is essential for the new module to work correctly.

Plug-and-Play Installation: Get Back on the Road Fast
Installing your new 1997 Cutlass PCM is a straightforward process that a confident DIYer can handle. No special tools are needed for the programming, as we’ve already done it for you.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes for any residual power to discharge.
- Locate the PCM: On most of these vehicles, the PCM is located in the engine bay, often inside the air filter housing or mounted to the firewall.
- Disconnect and Remove: Carefully unclip the wiring harness connectors. They often have locking tabs that need to be released. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed module into place. Reconnect the wiring harnesses, ensuring they click securely into position.
- Reconnect Battery: Reattach the negative battery terminal. The vehicle may need to complete a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes before starting.
