An ECU problem does not always announce itself with a clear warning light. Often it shows up as a collection of smaller symptoms that are easy to dismiss individually.
Signs Worth Watching For
Inconsistent idle, random limp mode entries, poor throttle response, unexplained fuel consumption changes, hesitant starting, intermittent warning symbols and stored codes that keep returning after being cleared are all worth taking seriously together.
Getting a Clear Diagnosis
The M-JET DIAGNOSTIC tool ties these symptoms back to specific stored codes, turning a vague feeling that something is off into an actual diagnosis.
