Is Your 1997 GM Vehicle Running Rough?
If you’re dealing with a persistent check engine light, poor fuel economy, erratic shifting, or even a no-start condition in your 1997 Chevrolet Lumina or other compatible GM model, the root cause is often a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, a faulty PCM can create a host of frustrating and difficult-to-diagnose problems. Don’t let a bad computer keep your reliable vehicle off the road. This is the direct, dependable solution you need to restore its performance and reliability.
This replacement Powertrain Control Module, part number 16217058 (also interchangeable with 16218070), is the definitive fix for these issues. We take the guesswork out of the repair by programming the module specifically for your vehicle using your VIN. This critical step ensures that the computer has the correct factory software and calibrations for your engine, transmission, and options package. It arrives at your door ready for installation, saving you a costly trip to the dealership for programming.
From the Diagnostic Bay
We had a 1997 Pontiac Grand Prix come into the shop that had its owner completely stumped. The car would randomly stall at stoplights and sometimes refuse to start for 10-15 minutes, with no check engine light. The owner had replaced the fuel pump and crank sensor, but the problem persisted. After hooking up our scanner and monitoring live data, we noticed the injector pulse width was dropping out intermittently just before a stall. All sensor inputs looked good, which pointed us directly to the PCM. The internal driver for the fuel injectors was failing under heat. We installed one of these VIN-programmed modules, performed the quick security relearn, and the car ran perfectly. It’s a classic example of how a failing PCM can mimic other component failures.
Common Symptoms of a Failing 1997 GM PCM
- ✔ Persistent and recurring Check Engine Light (CEL)
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Harsh or erratic automatic transmission shifting
- ✔ A complete no-start condition where the engine cranks but won’t fire
- ✔ Poor engine performance and reduced power
- ✔ Significantly decreased fuel economy
- ✔ Communication errors with diagnostic scan tools
- ✔ Failure to pass state emissions testing
Why a VIN-Programmed 1997 Lumina Powertrain Module is Essential
In modern vehicles, the PCM is not a one-size-fits-all part. It’s tailored to the specific vehicle it came from. Simply swapping a module from a junkyard vehicle will almost certainly result in a no-start condition due to security system conflicts (VATS/Passlock) and incorrect engine or transmission calibrations. Our professional programming service eliminates these headaches. By providing us with your Vehicle Identification Number (VIN) during checkout, you receive a module that is a true plug-and-play component for your exact vehicle. We load the latest GM-authorized software updates, which can often resolve factory bugs and improve overall performance and drivability.
Simple Installation Process
Replacing the PCM is a straightforward job for a DIY mechanic. It is typically located in the engine bay, often inside the air filter housing for protection. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and installing the new one in its place. After reconnecting the battery, you may need to perform a simple security relearn procedure, which can be done without any special tools. Instructions for this are widely available and easy to follow.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive an email with instructions. You can simply reply to that email with your 17-digit VIN, or include it in the ‘notes to seller’ section during checkout. We cannot ship your part until we receive the VIN.
Is this a plug-and-play part?
Yes, this module comes fully programmed to your vehicle’s VIN. In most cases, you will need to perform a simple security relearn procedure after installation, which takes about 30 minutes and does not require any special tools. This syncs the new module to your vehicle’s anti-theft system.
Will this fix my specific problem?
This module will correct any issues directly caused by a faulty PCM. While the symptoms listed are common indicators of PCM failure, it’s always recommended to have a proper diagnosis performed by a qualified mechanic to rule out other potential causes like bad sensors or wiring.
Do I need to send my old computer (core) back?
No core charge or return is required for this part. You can keep your old module or dispose of it responsibly.
