Restore Peak Performance to Your GM Vehicle
Is your 1998 Oldsmobile Intrigue, or another compatible GM vehicle, suffering from perplexing issues like a persistent check engine light, rough idling, poor fuel economy, or transmission shifting problems? These are classic signs of a failing Powertrain Control Module (PCM). The PCM is the central computer of your vehicle, responsible for managing the engine, transmission, and dozens of other critical systems. When it fails, it can cause a cascade of problems that are often difficult to diagnose. This replacement PCM, part number 09356741, is the definitive solution to get your car running smoothly and reliably again.
The Brains of the Operation: Why a Programmed PCM is Essential
Think of the PCM as your car’s brain. It takes in data from sensors all over the vehicle—oxygen sensors, throttle position, engine speed—and makes thousands of calculations per second to control fuel injection, spark timing, and transmission shift points. A generic, unprogrammed module from a parts store or salvage yard simply won’t work. It lacks the specific software and calibrations for your vehicle’s unique configuration. Our process eliminates this guesswork. We flash this module with the latest GM-certified software updates, programmed specifically to your vehicle’s Vehicle Identification Number (VIN). This ensures seamless communication between all onboard systems, restoring the original factory performance and efficiency.
From the Diagnostic Bay
We had a 1998 Pontiac Grand Prix come into the shop with a complaint of intermittent stalling and a check engine light that multiple other shops couldn’t solve. They had replaced the plugs, wires, and even the fuel pump. The codes were all over the place—misfires, O2 sensor faults, communication errors. After hours of diagnostics, we traced the issue back to the PCM. The internal processor was failing intermittently, sending corrupt data to the engine and transmission. We installed a VIN-programmed module just like this one, performed the security relearn procedure, and the car ran like it just rolled off the assembly line. The customer was thrilled to finally have a reliable car again. It’s a perfect example of how a faulty computer can mimic a dozen other mechanical problems.
Is Your Vehicle’s PCM Failing?
- ✔ Check Engine Light: The light is on, and you may have multiple, seemingly unrelated diagnostic trouble codes (DTCs).
- ✔ Poor Engine Performance: Your vehicle may experience rough idling, stalling, hesitation during acceleration, or a noticeable loss of power.
- ✔ Reduced Fuel Economy: A failing PCM can’t properly manage the air-fuel mixture, leading to a significant drop in MPG.
- ✔ Transmission Issues: You might notice harsh shifting, delayed engagement, or the transmission getting stuck in one gear (limp mode).
- ✔ No-Start Condition: In severe cases, a complete PCM failure can prevent the engine from starting at all, even if the battery and starter are good.
- ✔ Failed Emissions Test: Improper engine management will almost certainly lead to a failed smog or emissions inspection.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of engine and transmission function, from fuel injection and spark timing to automatic transmission shifting, to ensure optimal performance, fuel economy, and emissions.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) contains critical information about your car’s specific options, engine, transmission, and emissions equipment. We use the VIN to load the exact GM-approved software and calibrations onto the PCM, ensuring it works perfectly with your vehicle right out of the box.
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. However, after installation, you will likely need to perform a security relearn procedure (often called a VATS or Passlock relearn) to allow the vehicle to start. This procedure is simple and can be done without special tools. Instructions are widely available online for your specific model.
Will this fix my check engine light?
If the check engine light and associated codes are being caused by a faulty PCM, then yes, this part will resolve the issue. It’s crucial to ensure that the codes are not being caused by other failing sensors or mechanical components. A faulty PCM is often the root cause when multiple, unrelated codes are present.
Is this a new or used part?
This is a high-quality, inspected, and tested replacement part that has been programmed with the latest software for your vehicle. It is guaranteed to restore your vehicle’s functionality and performance.
