From the Technician’s Bench: We see these 1997-era PCMs all the time. After decades of heat cycles and vibrations, internal connections and processors can fail, leading to bizarre issues that seem impossible to track down. A common mistake is to grab a used computer from a salvage yard. While it might plug in, it won’t have the correct VIN, fuel trim data, or transmission strategy for your specific vehicle, leading to even more problems. Our process of programming the 16229684 PCM directly to your VIN is the only way to guarantee a correct and lasting repair, restoring the vehicle to its original factory operating parameters.
