Restore Peak Performance to Your 1997 GM Vehicle
Is your 1997 Buick Skylark, Grand Prix, or another GM model exhibiting strange behavior? Issues like a persistent check engine light, rough idling, stalling, or poor fuel economy often point to a failing Powertrain Control Module (PCM), the central computer of your vehicle. The PCM is responsible for managing critical engine and transmission functions, from fuel injection and ignition timing to emission controls and automatic shifting. When it falters, the entire driving experience suffers. This replacement Powertrain Control Module, part number 16218070, is the definitive solution to restore your vehicle’s original performance and reliability.
I remember a 1997 Buick Regal that came in with a complaint of intermittent stalling and a check engine light that no other shop could seem to fix. The codes were all over the place—random misfires, O2 sensor faults, and transmission communication errors. After verifying the wiring harness and grounds were solid (a common issue on these cars), we connected a scope to the PCM outputs. We saw the injector and ignition control signals dropping out randomly. It was a classic case of an internally failing computer. We installed a VIN-programmed PCM just like this one, performed the security relearn, and the car ran like it just rolled off the assembly line. The customer was thrilled to have their reliable car back without the guesswork.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Rough or erratic engine idle.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Vehicle fails to start, even with a good battery and starter.
- ✔ Misfire conditions that aren’t resolved by new plugs or coils.
- ✔ Failure to pass state emissions testing.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN at checkout, and the module will arrive with the correct software, ready for installation.
What is a VIN and why is it required?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific car. It contains information about the make, model, engine, and factory options. We use the VIN to load the exact GM-specified software for your vehicle, ensuring perfect compatibility and function.
Will this fix my check engine light?
If the Powertrain Control Module is the source of the fault codes, then yes, this part will resolve the issue and allow the check engine light to be cleared. However, if the light is on due to other failing components (like a bad sensor or wiring), those issues will still need to be addressed.
Is any special procedure needed after I install it?
After installation, you will likely need to perform a security relearn procedure, also known as a Passlock or CASE relearn. This syncs the new PCM with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions are widely available online or in service manuals.
Where is the PCM located on my 1997 vehicle?
On most of these 1997 GM models, the PCM is located in the engine bay, inside the air filter housing. This protects it from the elements while keeping it accessible for service. Always disconnect the battery before unplugging or removing the old module.
