Is Your 1998 Oldsmobile Intrigue Running Rough?
If you’re experiencing frustrating issues like a persistent check engine light, erratic engine behavior, poor fuel economy, or harsh transmission shifting, the problem may lie with a failing Powertrain Control Module (PCM). As the central computer 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 problems that are often difficult to diagnose, leaving you stranded or with an unreliable vehicle.
From the Diagnostic Bay
We had a 1998 Pontiac Grand Prix come into the shop last month with a list of complaints that had stumped two other mechanics. The owner reported random stalling at stoplights, a transmission that seemed to have a mind of its own, and a check engine light that would come and go. We scanned the codes and found a mix of communication errors and sensor faults that didn’t point to a single component. After verifying the wiring harness and checking grounds, our lead technician suspected the PCM. We installed one of our pre-programmed modules, performed the security relearn, and the car immediately ran like new. The owner was thrilled to have his reliable daily driver back. It’s a classic case of how a faulty computer can mimic a dozen other problems.
The Direct Solution: A VIN-Programmed 1998 Intrigue PCM
Don’t let a faulty computer keep you off the road. This Powertrain Control Module, service number 16236757, is the definitive solution for a wide range of 1998 and 1999 GM vehicles, including your Oldsmobile Intrigue. We take the guesswork and hassle out of the replacement process. Unlike a generic module from a parts store or a salvage yard unit with unknown history, our modules are meticulously tested and programmed specifically for your vehicle. We use your Vehicle Identification Number (VIN) to flash the unit with the latest, most stable software updates directly from GM. This ensures perfect compatibility and optimal performance, restoring your vehicle’s original drivability and efficiency.

- ✔ Engine stalling or stumbling for no apparent reason
- ✔ Rough or erratic idling
- ✔ Noticeable decrease in fuel economy
- ✔ Harsh, delayed, or incorrect transmission shifting
- ✔ Failure to pass emissions testing
- ✔ Vehicle won’t start, even with a good battery and starter
- ✔ Communication error codes with a diagnostic scan tool
Plug-and-Play Installation Process
Our goal is to make this repair as simple as possible. The process is straightforward:

Frequently Asked Questions
Do I need to get this module programmed?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during checkout, and it will arrive ready to be installed.
What is a VIN and where do I find it?
The VIN is your vehicle’s unique 17-digit identification number. You can typically find it on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What is a security relearn procedure?
After installing the new PCM, your vehicle’s anti-theft system may need to re-synchronize with the new module. This is a simple procedure that usually involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This allows the components to communicate and authorize the new PCM.
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 is always recommended to have a proper diagnosis performed to confirm the PCM is the root cause of the problem.
Is this part compatible with other GM vehicles?
Yes, this PCM (16236757) is compatible with a wide range of 1998-1999 GM models, including the Buick Century, Chevy Malibu, Pontiac Bonneville, and Oldsmobile Cutlass, among others. The VIN-specific programming ensures it works perfectly for any of the compatible vehicles listed.
