Is Your 1997 GM Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a vehicle you can’t rely on. If your 1997 Regal, Grand Prix, Lumina, or another compatible GM vehicle is suffering from a persistent check engine light, erratic shifting, stalling, or a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it affects your car’s performance, fuel economy, and safety. This replacement module is the definitive solution to restore your vehicle’s original reliability and give you peace of mind behind the wheel.

Expert Insight: The Critical Role of VIN Programming
As a technician, I’ve seen countless issues arise from using a generic or junkyard computer. On these 90s GM vehicles, the PCM is the central hub that communicates with the engine, transmission, and even the anti-theft system (VATS/Passlock). Flashing the 16217058 PCM with your exact VIN isn’t just a suggestion—it’s essential. It ensures the transmission shifts at the correct points for your specific gear ratio and that the anti-theft system recognizes the module, preventing a no-start situation. We take care of this critical step so you receive a part that works correctly the first time.
Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your car.
Will I need to do any additional programming after installation?
No. This 16217058 PCM arrives fully programmed and ready for installation. In some vehicles, a security relearn procedure may be required, which is a simple process that can be done without any special tools. Instructions can be easily found online or in your vehicle’s service manual.
Is this a difficult part to install myself?
For most of the listed models, the PCM is in an accessible location in the engine bay, often near the air filter box. Installation typically requires basic hand tools to disconnect the wiring harnesses and mounting bolts. Always disconnect the battery’s negative terminal before starting work.
What if my original part number is 16218070?
This module is a direct, compatible replacement for both part numbers 16217058 and 16218070. We will program it to function perfectly for your vehicle’s application.
What are the most common signs my PCM is failing?
The most common indicators are a steady Check Engine Light with internal processor fault codes, random stalling for no reason, poor fuel economy, and erratic automatic transmission behavior. If you’re experiencing a combination of these symptoms, the PCM is a very likely cause.
