Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected an electrical problem in the circuit for ignition coil K, which fires the spark plug on one cylinder. The common causes are a worn-out coil, damaged or shorted wiring, or a faulty connector. It's a common code and is normally fixed by replacing the bad coil and repairing any damaged wiring or connections.
$100 – $350
Varies by vehicle and root cause.
Short distances are usually okay, but you shouldn't rely on it. A misfiring cylinder can overheat and damage your catalytic converter, which is expensive to replace. If the car shakes badly or the light flashes, stop driving and have it towed.
Typical repairs run from $100 to $350. The ignition coil is fairly cheap and quick to install. Costs increase if connectors or wiring need work or if several coils are replaced together for reliability.
It should be addressed soon. A single misfire won't strand you immediately, but ignoring it risks catalytic converter damage and rough running. Don't let it linger longer than necessary.
Yes. A fouled or worn spark plug can put extra strain on coil K and trigger this code, so technicians often inspect the plug along with the coil. Replacing both together is common to ensure the misfire is fully resolved.
