Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected a misfire on cylinder 5, where the air-fuel mixture isn't igniting correctly. The usual culprits are a worn spark plug, a failing ignition coil, or a fuel injector issue, though vacuum leaks and low compression are also possible. Typical fixes involve replacing the spark plug or coil for cylinder 5, and most cases are repairable without tearing into the engine.
$100 – $500
Varies by vehicle and root cause.
Only briefly and gently. A misfiring cylinder 5 sends unburned fuel into the exhaust and can damage your catalytic converter fast. If the light is flashing, stop and tow it; if steady, drive carefully straight to a mechanic.
Typically $100 to $500. A spark plug or single coil is inexpensive, while injector or compression repairs cost more. A proper diagnosis first avoids guessing and replacing parts unnecessarily.
Yes. Misfires are serious because they can ruin the catalytic converter and leave you with a much bigger bill. The upside is that the root cause is often a cheap, common part like a plug or coil.
Definitely. While plugs and coils are the most common causes, a clogged injector, a vacuum leak, or low compression on cylinder 5 can also trigger it. That's why a scan and a few quick tests are worth doing before buying parts.
