Is Your Oldsmobile Intrigue Acting Up?
If you’re dealing with a frustrating no-start condition, erratic transmission shifting, a persistent Check Engine Light, or poor fuel economy, a failing Powertrain Control Module (PCM) is often the culprit. In my 20+ years as a technician, I’ve seen these symptoms countless times on late-90s GM vehicles. The PCM is the brain of your car, and when it starts to fail, it can cause a cascade of confusing problems that are difficult to diagnose.
From the Shop Floor: A Real-World Scenario
“A customer’s 1998 Grand Prix (which uses this exact same module) came into my shop last month. It would randomly stall at stoplights and had a harsh 1-2 shift. They had already replaced the fuel pump and the ignition control module with no success. After connecting my scanner, I noticed the PCM wasn’t commanding the torque converter clutch correctly, and injector pulse width was erratic. A quick swap with one of our tested PCMs confirmed the diagnosis. The original module’s driver circuits were failing internally—a common issue. This pre-programmed module would have saved them hundreds in unnecessary parts and labor.”
