Is Your Oldsmobile Intrigue Running Rough?
If you’re dealing with a persistent Check Engine Light, unpredictable stalling, poor acceleration, or harsh transmission shifting, the problem often points directly to a failing Powertrain Control Module (PCM). As a technician with over two decades of experience under the hood, I’ve seen these exact issues on countless late-90s GM vehicles. The PCM is the electronic brain of your engine and transmission, and when it starts to fail, it can create a cascade of frustrating and hard-to-diagnose problems.
The Simple, Reliable Solution for Your 1998 Intrigue PCM
Forget expensive dealership visits and the hassle of finding a local shop that can program older modules. This replacement PCM, part number 16236757, is the definitive fix. We take all the guesswork out of the repair. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) during checkout, and our technicians will program the module with the latest official GM software updates specific to your car. It arrives at your door ready for a straightforward, plug-and-play installation.
Real-World Diagnosis: A Technician’s Story
“A customer’s 1998 Buick LeSabre, which uses this exact same PCM, came into my shop last week with an intermittent no-start and a random cylinder misfire code that kept moving. The owner had already replaced the plugs, wires, and ignition control module. After hooking up my diagnostic scanner and seeing erratic data from the crank sensor, I knew the issue wasn’t the sensor itself, but the PCM’s interpretation of its signal. A failing processor inside the original module was the culprit. We installed one of our VIN-programmed PCMs, and the car fired right up and has run flawlessly since. This is a classic failure mode I’ve seen hundreds of times on these GM 3.8L and 3.1L engines.”
Common Symptoms of a Failing PCM:
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or cutting out while driving
- ✔ Difficulty starting the engine or a no-start condition
- ✔ Poor fuel economy
- ✔ Erratic or harsh automatic transmission shifting
- ✔ Failed emissions test
- ✔ Unexplained diagnostic trouble codes (DTCs)
Plug-and-Play Installation: No Dealer Visit Required
Installing your new PCM is a job most DIY mechanics can handle in their own driveway. While the exact location can vary slightly by model, it’s typically found in the engine bay inside the air cleaner assembly.
- Safety First: Disconnect the negative terminal from your car’s battery.
- Locate the PCM: Open the air filter box. The PCM is the silver metal box with multiple large electrical connectors.
- Disconnect: Carefully unclip and remove the electrical harness connectors from the old module.
- Remove Old Unit: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install New Unit: Mount your new, pre-programmed PCM in its place and securely reconnect the electrical harnesses. You should hear a ‘click’ as they lock in.
- Reconnect Power: Re-attach the negative battery terminal. Your vehicle is now ready to start.
