Restore Peak Performance to Your Vehicle with a Programmed PCM
Is your Oldsmobile Intrigue or other GM vehicle suffering from frustrating engine problems? A faulty Powertrain Control Module (PCM) is often the hidden culprit behind issues like stalling, rough idling, poor fuel mileage, and a stubborn check engine light. As a technician with over 20 years of experience, I’ve seen how a failing engine computer can mimic a dozen other problems, leading to expensive and unnecessary repairs. This thoroughly tested, used PCM, part number 09361735, is the reliable and economical solution to get your car running smoothly again.
The biggest hurdle in replacing a PCM is the programming. This module solves that problem for you. Before we ship it, we will flash the unit with the latest official GM software updates, tailored specifically to your car’s Vehicle Identification Number (VIN). This ensures seamless communication with your engine, transmission, and security system, making the installation process as simple as possible.
Common Signs of a Failing PCM
If you’re experiencing any of the following, a faulty engine computer could be the cause. In the shop, we frequently see these symptoms linked to internal PCM failure, often accompanied by diagnostic trouble codes (DTCs) like P0601, P0605, or P0606.
- ✔ Unexplained stalling or engine shutting off while driving
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Noticeable decrease in fuel economy
- ✔ Engine cranks but refuses to start
- ✔ Persistent Check Engine Light that won’t clear
- ✔ Communication errors with scan tools
Case Study: The Ghost in the Machine
A customer brought in a 2000 Pontiac Grand Prix 3.8L with an issue that was driving him crazy. The car would run perfectly for days, then suddenly stall at a stoplight and refuse to restart for 10-15 minutes. He’d already replaced the crank sensor and fuel pump with no luck. After connecting my diagnostic scanner, I noticed intermittent communication loss with the PCM. On these older GM platforms, heat soak can cause internal solder joints in the computer to fail. We swapped in a pre-programmed PCM just like this one, and the problem vanished instantly. It was a 30-minute fix that solved a month-long headache for the owner.
A Straightforward Guide to Installation
Installing your programmed PCM is a manageable job for a confident DIYer. Following these steps will help ensure a smooth process.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes for the system capacitors to discharge.
- Locate the PCM: On most compatible vehicles like the 1999 Intrigue, the PCM is located in the engine compartment, typically inside the air filter box assembly for protection. Refer to your vehicle’s service manual for the exact location.
- Disconnect Connectors: Carefully unclip and remove the electrical wiring harnesses from the old PCM. Inspect the connectors for any corrosion or bent pins.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your replacement PCM securely onto the bracket and reconnect the wiring harnesses. Ensure they click firmly into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Security Relearn: You will likely need to perform a simple security relearn procedure (often called VATS relearn) so the vehicle recognizes the new PCM. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times.
