Restore Peak Performance to Your GM Vehicle
Is your 1998 Oldsmobile Intrigue, Grand Prix, or another compatible GM vehicle suffering from frustrating issues like a persistent check engine light, poor fuel economy, erratic shifting, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM). The PCM is the electronic brain of your vehicle, managing critical engine and transmission functions. When it falters, the entire driving experience is compromised. This replacement PCM, part number 9366314, is the definitive solution to restore your vehicle’s reliability and performance.
We had a 1998 Buick LeSabre with the 3.8L V6 come in that was driving the owner crazy. It had a random, intermittent misfire that wouldn’t set a specific cylinder code. The owner had already replaced spark plugs, wires, and the ignition coil pack. We hooked up our diagnostic scanner and monitored the live data. Everything looked normal until, for a split second, the injector pulse for cylinder 3 would drop out. It wasn’t the injector or the wiring; it was a failing driver inside the original PCM. We installed one of these VIN-programmed modules, performed the security relearn, and the car ran perfectly. It’s a great reminder that sometimes the problem lies with the component controlling everything else.
Symptoms of a Failing 1998 Intrigue Powertrain Control Module
- ✔ Persistent Check Engine Light (CEL) illumination.
- ✔ Engine stalling, stumbling, or running rough.
- ✔ Harsh or unpredictable automatic transmission shifting.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ The vehicle fails to start or has intermittent starting problems.
- ✔ Failure to communicate with diagnostic scan tools.
- ✔ Inability to pass state emissions testing.
The Plug-and-Play Solution
What sets this module apart is our professional programming service. Forget expensive trips to the dealership for flashing and setup.

Frequently Asked Questions
What exactly does the Powertrain Control Module (PCM) do?
The PCM is your vehicle’s central computer. It takes information from sensors all over the engine and transmission to control fuel injection, ignition timing, emissions systems, and automatic transmission shift points to ensure the vehicle runs efficiently and smoothly.
Why do you need my VIN for programming?
Your Vehicle Identification Number (VIN) contains specific information about your car’s engine, transmission, emissions systems, and other factory-installed options. Programming the PCM with your VIN ensures it has the exact software calibration for your specific vehicle, making it a true plug-and-play part.
Is this part difficult to install?
For most DIY mechanics, installation is straightforward. It typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one in the reverse order. No special tools are usually required.
Will I need to do anything after installation?
In many cases, after installing the new PCM and reconnecting the battery, you may need to perform a simple security relearn procedure (often called a CASE learn or Passlock relearn). This procedure syncs the new module with your vehicle’s anti-theft system and can typically be done without any special tools. Instructions are widely available online for your specific model.
Will this fix my check engine light?
If the check engine light is on due to a fault within the old PCM itself (such as internal processor errors or communication faults), this new module will resolve the issue. However, if the light is on because of a faulty sensor or other component, that part will still need to be addressed.
Is this part compatible with my 1998 Grand Prix?
Yes, this PCM is compatible with the 1998 Pontiac Grand Prix, as well as a wide variety of other GM cars from that era. Please refer to the detailed fitment list on this page to confirm compatibility with your exact model and engine combination.
