Restore Peak Performance to Your 1997 GM Vehicle
Is your 1997 Grand Prix, Bonneville, or Regal suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or erratic transmission shifting? A failing Powertrain Control Module (PCM) is often the hidden culprit behind these problems, acting like a confused brain for your vehicle’s most critical systems. This is your direct, reliable solution to restore the smooth, dependable performance you expect from your car. We provide a top-quality PCM that is professionally programmed to your specific vehicle using your VIN, ensuring a seamless and effective repair.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, often mimicking other component failures and leading to costly, incorrect repairs. If you’re experiencing any of the following, this module is the definitive fix:
- Unexplained Check Engine Light with codes like P0601 (Internal Control Module Memory Check Sum Error)
- Poor or declining fuel economy
- Hesitation or stumbling during acceleration
- Harsh or unpredictable automatic transmission shifts
- Engine stalling or refusing to start
- Misfire codes (e.g., P0300) that persist after replacing plugs, wires, and coils
Instead of just selling you a part, we deliver a complete, ready-to-install solution. By using your Vehicle Identification Number (VIN), we flash this Programmed 19109047 PCM with the latest, most stable software updates from GM. This critical step ensures the module communicates perfectly with your engine, transmission, anti-lock brakes, and security system right out of the box.

From the Shop Floor: The “Ghost in the Machine” Fixed
We recently worked on a ’97 Regal GS that had been to three other shops for a persistent misfire (P0300). The owner had spent a fortune on new plugs, wires, ignition coils, and even a crank sensor, but the problem always returned. The real culprit? The original PCM was failing intermittently, sending corrupt data to the ignition system. Once we installed a properly Programmed 19109047 PCM matched to the car’s VIN, it ran like a top. This isn’t just a part; it’s the solution that fixes the root cause when the vehicle’s brain is the problem.
Frequently Asked Questions
Do I need to have this programmed by a dealer?
No. The main benefit of our service is that we handle all the programming for you before we ship. The module will arrive flashed to your vehicle’s specific VIN with the latest GM updates, saving you a trip to the dealership and their high programming fees.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to do this. We cannot ship your part until we receive and validate your VIN, as the programming is essential for the part to function.
Is this a simple plug-and-play installation?
Yes, for the vast majority of vehicles, this is a direct plug-and-play installation. Once installed, you should perform a security relearn procedure (often called a Passlock or VATS relearn), which is a simple process that typically involves turning the key on and off in a specific sequence. Instructions for this are widely available online for your specific model.
Will this fix my specific problem or check engine light?
If your vehicle’s issues have been correctly diagnosed as a faulty PCM, then this part is the solution. It is designed to resolve problems directly caused by the control module, including many common diagnostic trouble codes. However, it will not fix issues caused by other faulty mechanical or electrical parts (e.g., a bad sensor or wiring).
Is this compatible with my supercharged 3.8L engine?
Absolutely. This Programmed 19109047 PCM is fully compatible with the vehicles listed, including the supercharged 3.8L V6 (L67) found in models like the Grand Prix GTP, Bonneville SSEi, and Regal GS. The VIN-specific programming ensures it has the correct fuel and timing maps for your exact engine configuration.
