Drivable short-term, but fix now to avoid damage.
This code means the engine computer found that cylinder 10 is contributing too little or too much power compared to the other cylinders, upsetting the engine's balance. It usually points to a clogged or weak fuel injector, low compression, a vacuum leak, or an ignition problem on that cylinder. Fixing it typically involves cleaning or replacing the injector and checking the cylinder's compression and spark.
$150 – $700
Varies by vehicle and root cause.
Short trips are usually fine, but don't let it linger. An imbalanced cylinder makes the engine run rough and can damage the catalytic converter over time, so get it checked soon.
Repairs typically range from $150 to $700. Cleaning or replacing an injector is at the lower end, while compression-related or ignition repairs can push the cost higher.
Yes, it's fairly serious because a cylinder isn't working properly. The car may still drive, but the rough running and potential converter damage make prompt repair worthwhile.
Not always. It can also stem from low compression, a vacuum leak, or an ignition issue on cylinder 10, so a technician will usually run a compression and balance test to find the true cause.
