Restore Your GM Vehicle’s Engine Performance
The Powertrain Control Module (PCM), also known as the Electronic Control Module (ECM), is the central computer of your 1997 Buick Regal and other compatible GM vehicles. It is responsible for managing every critical aspect of your engine and transmission’s operation, from fuel injection and ignition timing to transmission shift points and emissions controls. When this vital component begins to fail, it can lead to a cascade of frustrating and performance-robbing issues. This replacement module, part number 16217058, is the definitive solution to restore your vehicle’s original performance, reliability, and efficiency.
From the Diagnostic Bay
We once had a 1997 Pontiac Grand Prix with the 3.8L V6 come into the shop. The owner was frustrated, having already replaced the crank sensor, ignition coils, and spark plug wires trying to solve an intermittent stalling and hard-start problem. The check engine light was on, but the codes were inconsistent. Our advanced diagnostics showed a complete loss of communication with the PCM at random intervals. The internal processor was failing. We installed a pre-programmed module just like this one, using the car’s VIN to ensure a perfect software match. After a quick security relearn, the car started instantly and ran smoother than it had in years. It’s a classic case where chasing sensors was a waste of time and money; the root cause was the vehicle’s main computer.
Is Your Powertrain Control Module Failing?
A faulty PCM can manifest in various ways, often mimicking other sensor or component failures. If you’re experiencing any of the following symptoms, a failing computer is a likely culprit. This replacement 1997 Regal Powertrain Module is designed to correct these common problems.
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Engine stalling for no apparent reason or difficulty starting.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough idling, engine hesitation, or misfires.
- ✔ Harsh, erratic, or delayed automatic transmission shifting.
- ✔ Failure to pass state emissions inspections.
- ✔ Complete loss of communication with diagnostic scan tools.
