Drivable short-term, but fix now to avoid damage.
This code means your engine's computer detected that cylinder 7 is misfiring, meaning it isn't burning the fuel-air mixture completely or at the right time. It's usually caused by worn spark plugs, bad ignition coils, fuel injector problems, or low compression in that cylinder. The fix often starts with replacing spark plugs and coils, and it's a common repair that doesn't always require major engine work.
$150 – $1200
Varies by vehicle and root cause.
For a very short trip, maybe, but it's risky. A misfire can damage your catalytic converter and worsen quickly, especially if the check engine light is flashing. It's best to get it diagnosed right away.
Most repairs run between $150 and $1,200, depending on the cause. A simple spark plug or coil replacement is on the lower end, while injector or compression-related issues cost more.
Yes, it can be. A misfire wastes fuel, hurts performance, and can damage expensive emissions parts if ignored. A flashing check engine light makes it more urgent.
The code pinpoints cylinder 7 specifically, so the problem is usually local to that cylinder, like its spark plug, coil, or injector. Swapping that coil with a neighboring one can help confirm the source.
