Restore Your GM’s Performance and Reliability
Is your trusty 1997 GM vehicle suffering from erratic engine behavior, poor fuel economy, or a persistent Check Engine light? A failing Powertrain Control Module (PCM) is often the root cause of these frustrating issues, compromising your car’s performance and dependability. This fully programmed engine computer is the direct-fit, reliable solution to get your car back on the road, running smoothly and dependably, just like it was designed to.
Common Symptoms & Your Solution
If you’re experiencing any of the following problems, a faulty PCM is the likely culprit. This unit is designed to be the definitive fix for these issues:
- Unexpected stalling or rough idling
- Difficulty starting the engine or a complete no-start condition
- Poor acceleration and loss of power
- Harsh or erratic automatic transmission shifting
- A steady or flashing Check Engine Light (CEL)
- Diagnostic Trouble Codes (DTCs) related to sensors, communication, or processor failure
- Reduced fuel economy
Installing our Programmed 1997 GM PCM 16218070 resolves these problems by restoring the critical link between your engine, transmission, and other vehicle systems with fresh, updated software tailored specifically to your car.

An Expert’s Note on VIN Programming: Many people think you can just swap a computer from a junkyard car. For these 90s GM vehicles, that’s a recipe for failure. The PCM is the brain, and it’s tied to your specific vehicle’s options and security system (like GM’s Pass-Key II). Our VIN-specific programming ensures the new module communicates perfectly with every other component, from the transmission to the anti-theft system. It’s the difference between a quick, successful repair and a car that won’t even start.
