Engine Misfire: Symptoms & Causes
A misfire makes the engine stumble and can damage the catalytic converter. A Cranbourne West specialist explains.
What it usually means
A misfire (the engine stumbling, shaking, hesitating or running rough, often with a flashing check-engine light) means a cylinder isn’t firing properly. Common causes are worn spark plugs, a failing ignition coil, an injector issue, a vacuum leak, or low compression.
A flashing check-engine light during a misfire is a warning that the catalytic converter is at risk.
What you should do
Get it diagnosed promptly — a persistent misfire wastes fuel, runs rough and can destroy an expensive catalytic converter.
We read the misfire data to identify the cylinder and cause, then fix the actual fault rather than guessing.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.
