Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected a fault in the electrical circuit for ignition coil L, which provides spark to one of the cylinders. It typically points to a failing coil, damaged or shorted wiring, or a loose or corroded connector. It's a common code and is usually fixed by replacing the affected coil and repairing any wiring issues.
$100 – $350
Varies by vehicle and root cause.
Usually for a short trip, but not for long. A misfiring cylinder can overheat and damage your catalytic converter, leading to a far bigger expense. If the engine shakes badly or the light flashes, stop and have the vehicle towed.
Most repairs cost between $100 and $350. The coil itself is affordable and quick to swap out. The bill grows if wiring or connectors need attention or if a technician replaces several coils at once.
It's worth fixing promptly. A single misfire won't immediately strand you, but it can damage emissions parts and make the engine run rough if left alone. Plan to repair it soon rather than waiting.
No. This code points to one ignition coil, not the entire engine. Replacing the faulty coil L and checking its wiring usually restores normal running without major engine work.
