Is Your 1997 GM Vehicle Running Rough?
Are you dealing with a persistent check engine light, erratic engine behavior, or transmission shifting problems in your 1997 Buick Skylark or other compatible GM vehicle? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your vehicle’s most critical functions. A faulty PCM can disrupt everything from fuel delivery and ignition timing to automatic transmission shifts, leading to a frustrating and unreliable driving experience. Don’t let a malfunctioning computer keep you off the road. This direct-fit replacement PCM, part number 16217058, is the reliable solution to restore your vehicle’s performance and dependability.
The Brain of Your Vehicle, Restored
The PCM is arguably the most important electronic component in your car. It constantly analyzes data from dozens of sensors to make real-time adjustments, ensuring optimal engine performance, fuel efficiency, and low emissions. When it fails, the symptoms can be widespread and confusing. This replacement module is meticulously prepared to take command once again. We pre-program it using your vehicle’s unique Vehicle Identification Number (VIN), loading the latest GM factory software updates. This ensures it communicates perfectly with all the other modules and sensors in your car, just like the original unit did when it was new. This isn’t a generic, one-size-fits-all part; it’s a component specifically calibrated for your exact vehicle.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling or cutting out for no apparent reason.
- ✔ Rough or inconsistent idling.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh, erratic, or delayed automatic transmission shifting.
- ✔ Failure to pass an emissions test.
- ✔ The engine cranks but refuses to start (no-start condition).
- ✔ Misfire codes that don’t resolve after replacing plugs, wires, or coils.

Frequently Asked Questions
Do I need to have this module programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready to install with the latest GM software for your specific vehicle.
Where can I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my car’s problems and turn off the check engine light?
If the Powertrain Control Module is the root cause of the issues, then yes, this part will resolve them and allow the check engine light to be cleared. However, if there are other underlying mechanical or electrical problems, those will need to be addressed separately.
Is any special procedure needed after I install it?
In many cases, it is a simple plug-and-play installation. However, some GM vehicles of this era may require a simple security relearn procedure (often called a Passlock or Passkey relearn) to allow the vehicle to start. This procedure can typically be done without any special tools and instructions are widely available online.
How can I be sure my old PCM is bad?
The best way to be certain is to have a qualified mechanic perform a complete diagnostic. However, symptoms like multiple unrelated error codes, stalling, and erratic shifting that persist after other components have been checked are strong indicators of a failing PCM.
