Restore Peak Performance to Your GM Vehicle
Is your 1998-1999 Oldsmobile Cutlass, Pontiac Grand Am, or other GM vehicle experiencing frustrating issues like stalling, rough idling, or erratic transmission shifting? The Powertrain Control Module (PCM), the central computer of your vehicle, is often the root cause of these perplexing problems. This replacement PCM, part number 9366314, is the definitive solution to restore your car’s original drivability, reliability, and efficiency. Unlike a generic part from a salvage yard, this module arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN), ensuring a seamless installation and proper function right out of the box.
From the Diagnostic Bay
We once had a 1998 Buick LeSabre in the shop that the owner was convinced needed a new transmission. It was shifting harshly between first and second gear and would occasionally refuse to go into overdrive, triggering a check engine light. He had already spent a significant amount of money on a fluid service and solenoid pack with no improvement. After connecting our diagnostic tools, we noticed that the command signals from the PCM to the transmission were erratic and inconsistent. We installed a correctly programmed PCM, and instantly, the shifting became smooth and precise. The ‘bad transmission’ was simply a faulty computer. This highlights how critical a fully functional 1998-1999 Cutlass PCM is to the entire vehicle, saving drivers from unnecessarily expensive repairs.
Common Symptoms of a Failing PCM
- ✔ Unexplained Check Engine Light that won’t clear or returns intermittently.
- ✔ Engine stalling for no apparent reason, either while driving or at idle.
- ✔ Difficulty starting the engine, even with a good battery and starter.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh, delayed, or incorrect automatic transmission shifts.
- ✔ The vehicle entering ‘limp mode,’ with reduced power.
- ✔ Failure to pass state emissions testing due to module-related codes.
- ✔ Communication errors with diagnostic scan tools.
The Importance of VIN-Specific Programming
In modern vehicles, the PCM is not a one-size-fits-all component. It must be calibrated for your car’s specific engine, transmission, and factory options. Attempting to install a non-programmed module will often result in a no-start condition or a host of new performance issues. We eliminate this headache. When you order, you provide us with your VIN. Our technicians then flash the module with the latest, most stable software updates directly from GM. This process ensures that your vehicle benefits from any factory-issued fixes for common drivability problems, delivering performance that is often better than the original.
