Is Your 1997 GM Vehicle Running Rough?
If you’re dealing with a persistent check engine light, erratic engine behavior, harsh shifting, or even a no-start condition in your 1997 Chevrolet Lumina, the problem often points directly to the vehicle’s brain: the Powertrain Control Module (PCM). As a technician with over two decades of experience under the hood, I’ve seen countless drivers replace expensive sensors and parts, only to find the root cause was a failing PCM all along. This module is the central command unit for your engine and transmission, and when it falters, the entire vehicle’s performance suffers.
A Technician’s Real-World Experience
“A customer’s 1997 Buick Regal came into my shop last month with these exact symptoms. It had intermittent stalling, terrible gas mileage, and a whole list of confusing diagnostic codes that didn’t seem related. After confirming the wiring and sensors were good, we pinpointed the original ECM. We installed one of our VIN-programmed modules, and it was a night-and-day difference. The engine smoothed out instantly, the codes cleared, and the customer was thrilled to have their reliable car back without a massive dealership bill.”

Plug-and-Play Installation: No Dealer Visit Required
You can get your vehicle back on the road with basic hand tools. Follow these simple steps to replace your old module.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the PCM: On most of these 1997 GM models, the PCM is located in the engine compartment, typically inside the air filter housing for protection.
- Disconnect Harnesses: Carefully unclip and remove the electrical wiring harnesses connected to the old module.
- Remove Old Unit: Unbolt the mounting hardware holding the original PCM in place and remove it from the vehicle.
- Install New PCM: Mount your new, pre-programmed module in the same location.
- Reconnect Everything: Securely plug the wiring harnesses back into the new PCM and reconnect the negative battery terminal.
- Final Step: In some cases, a simple security relearn procedure may be needed, which can be done without special tools. Instructions are readily available online for your specific model.
Expert Pro Tip: Ensure a Perfect Connection
Before plugging in your new PCM, take 60 seconds to inspect the vehicle’s harness connectors. Over the years, pins can get slightly corroded or bent. Use a small pick to ensure all pins are straight and a can of electronics-safe contact cleaner to spray the connectors. This simple step ensures a clean, solid connection and prevents frustrating, hard-to-diagnose issues down the road.
