Is Your GM Vehicle Running Rough?
If your 1997 Monte Carlo, Grand Prix, Lumina, or another GM vehicle from that era is suffering from a persistent check engine light, erratic performance, stalling, or poor fuel economy, a failing Powertrain Control Module (PCM) is often the culprit. As the central computer of your vehicle, its health is critical for everything from engine timing to transmission shifting. Don’t let a faulty computer keep you off the road. This is the reliable, straightforward solution to get your car running smoothly again.

- Harsh or Erratic Shifting from the automatic transmission.

Expert Insight: The ‘Phantom Problem’ Solver
As a technician, I’ve seen countless hours and dollars wasted chasing problems that weren’t there. A customer once brought in a ’97 Regal with a persistent, random misfire that new plugs, wires, and coils couldn’t fix. After extensive diagnostics, we traced it to a weak injector driver inside the original PCM. Instead of more guesswork, we installed a pre-programmed module just like this one. The problem vanished instantly. This isn’t just a part; it’s often the solution that saves you from a frustrating and expensive diagnostic rabbit hole. Getting a properly programmed 1997 Monte Carlo PCM 16217058 is the key to a successful repair.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM is delivered to you fully programmed and ready for installation. We handle all the flashing using your vehicle’s VIN, so you can install it right out of the box.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you a message requesting your VIN. We cannot ship your part until we receive this information, as it is essential for programming the module correctly.
How do I know if this part will fit my car?
Please check the detailed fitment list on this page. This module is a direct replacement for part numbers 16217058 and 16218070 and fits a wide range of 1997 GM models. Matching your original part number is the best way to ensure compatibility.
Will this fix my check engine light?
This module will resolve any check engine light and performance issues directly caused by a faulty PCM. If the light is on due to other issues (e.g., a bad oxygen sensor or catalytic converter), those problems will need to be addressed separately.
Is the installation difficult?
For most DIYers, the installation is straightforward. It typically involves disconnecting the vehicle’s battery, locating the old PCM, unplugging the wiring harnesses, unbolting it, and then installing the new one in reverse order. Basic hand tools are all that’s required.
