Common Symptoms of a Failing 1997 Grand Am ECM

A faulty engine computer can manifest in numerous ways, often intermittently at first. If you’re experiencing any of the following, it’s highly likely your ECM is the culprit:

• ✔ Check Engine Light: The most common indicator, often with codes related to module communication, sensor circuits, or processor faults.
• ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly while driving or at a stop, accompanied by rough running or misfires.
• ✔ No-Start Condition: The engine cranks but refuses to start, indicating a potential loss of fuel injector or ignition coil control from the ECM.
• ✔ Poor Fuel Economy: Incorrect fuel and air calculations by a failing module can lead to a noticeable drop in your MPG.
• ✔ Harsh or Erratic Shifting: As a PCM, this module also controls transmission functions. You may experience delayed, hard, or incorrect gear shifts.
• ✔ Failure to Communicate: A diagnostic scan tool may be unable to connect with the ECM, a clear sign of an internal module failure.
