Drivable short-term, but fix now to avoid damage.
This code means your engine's computer detected a misfire in cylinder 11, so that cylinder isn't burning its fuel-air mixture the way it should. Common causes include worn spark plugs, a failing ignition coil, a clogged injector, or low compression. The fix usually begins with replacing spark plugs and coils, and it's a common repair that's often manageable without major engine work.
$150 – $1200
Varies by vehicle and root cause.
Only briefly if there's no other option. A misfire can damage your catalytic converter and get worse fast, especially with a flashing light. Have it diagnosed promptly.
Repairs generally run $150 to $1,200. Spark plugs and coils are cheaper, while injector or compression problems push costs higher.
Yes. A persistent misfire reduces power, wastes fuel, and can damage costly emissions components. A flashing check engine light makes it urgent.
Cylinder 11 is found only on large engines like V12s, common in some luxury and exotic vehicles. Parts and labor can be expensive, so a careful diagnosis before replacing components is worth it.
