Is Your GM Vehicle Running Rough? Get Back on the Road Fast.
If you’re dealing with a persistent check engine light, erratic engine performance, poor fuel mileage, or even a no-start condition in your 1998 Oldsmobile Intrigue or other compatible GM vehicle, a failing Powertrain Control Module (PCM) is often the culprit. As the brain of your vehicle, when the PCM starts to fail, it can cause a cascade of frustrating and hard-to-diagnose issues. In my 20+ years in the shop, I’ve seen these exact modules cause everything from harsh transmission shifts to unexplained stalling. This isn’t just a part; it’s the solution to getting your car’s reliability and performance back.
The Smart Solution: A VIN-Programmed PCM
Forget the hassle and high cost of a dealership visit. We send you a fully tested PCM that is professionally programmed with the latest official GM software updates, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN). This ensures perfect communication between the module and all your vehicle’s systems, right out of the box. Just provide us with your VIN after purchase, and we handle the rest.
Expert Pro Tip: Check Your Connections First
Before installing your new PCM, take a moment to inspect and clean the main harness connectors. Over two decades, it’s common for a thin layer of oxidation to form on the pins, which can cause poor contact and mimic the symptoms of a failing module. A quick spray with an electronics-safe contact cleaner and a gentle scrub with a small brush can ensure a perfect connection and prevent future headaches. It’s a five-minute job that guarantees your new part performs flawlessly from day one.

- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or misfiring
- ✔ Poor or inconsistent fuel economy
