Is It Safe to Drive with a Misfire

Your engine is shaking, the check engine light is flashing, and you can feel the power loss. A misfiring engine is telling you something is wrong right now.

Driving with a misfire is not recommended, especially if the check engine light is flashing. A flashing check engine light specifically means active catalytic converter damage is occurring — unburned fuel is entering the exhaust system and overheating the catalytic converter, which can cost $1,000 or more to replace. A steady check engine light with a mild misfire is less immediately urgent but should still be diagnosed soon to prevent further damage.

An engine misfire means one or more cylinders aren't firing properly. The most common causes are worn spark plugs, failed ignition coils, faulty fuel injectors, vacuum leaks, low compression, or a clogged catalytic converter restricting exhaust flow. A diagnostic scan tool reads the misfire code and identifies which cylinder is affected. From there, the mechanic tests the ignition coil, spark plug, injector, and compression for that cylinder to find the root cause.
