Is Your Oldsmobile Intrigue Running Rough? The PCM Might Be the Culprit.
If your 1998 Oldsmobile Intrigue is suffering from issues like a persistent check engine light, erratic shifting, poor fuel economy, or even a no-start condition, the problem may lie with its central computer: the Powertrain Control Module (PCM). As the brain of your vehicle, the PCM is responsible for managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it begins to fail, it can cause a cascade of frustrating and difficult-to-diagnose problems.
This replacement Powertrain Control Module, part number 9366314, is the definitive solution to restore your vehicle’s performance and reliability. We take the guesswork out of the repair by programming the module specifically for your vehicle using your VIN. This ensures that it arrives with the latest GM software updates, ready for a straightforward installation without the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 1998 Pontiac Grand Prix come into the shop with a complaint of harsh, unpredictable shifting and a check engine light that multiple other shops couldn’t solve. The owner had already replaced the transmission speed sensors and the throttle position sensor, spending hundreds on parts that didn’t fix the issue. After hooking up our professional scan tool, we noticed erratic data coming from the PCM. The internal processors were failing, sending corrupt signals to the transmission. We installed one of our VIN-programmed modules, and the car immediately shifted smoothly, and the check engine light stayed off. It’s a classic case of symptoms pointing to one area while the root cause is the central computer itself.
Symptoms of a Failing Powertrain Control Module
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Unexplained drop in fuel mileage
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass emissions testing
- ✔ Intermittent no-start or hard-starting conditions
- ✔ Loss of power and poor acceleration

Frequently Asked Questions
Why do you need my VIN?

This includes engine size, transmission type, and other options. This step is critical for ensuring the module works perfectly 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. Because we pre-program the unit, you avoid the most complex part of the job. Some vehicles may require a simple security relearn procedure, which we can provide instructions for.
Will this fix my check engine light?
If the check engine light and other symptoms are caused by a faulty PCM, this replacement part is the correct solution. It’s important to have properly diagnosed the issue to ensure the PCM is the root cause and not a faulty sensor or wiring problem.
