Random/Multiple Cylinder Misfire Detected
The engine computer has detected misfires in one or more cylinders, but not limited to a single cylinder. This usually means the engine is not burning fuel correctly because of bad ignition parts, fuel delivery problems, air leaks, sensor faults, or internal engine issues.
You may be able to drive short distances, but the engine may run poorly, stall, or lose power. Continued driving can damage the catalytic converter and may make the vehicle unsafe in traffic.
P0300 means the powertrain control module has detected random or multiple cylinder misfires. Because the misfire is not isolated to one cylinder, diagnosis usually involves checking ignition, fuel, air metering, vacuum leaks, and mechanical engine condition. The code may appear with other misfire codes, fuel trim codes, or sensor-related codes that help identify the root cause.
It means the engine computer detected random or multiple cylinder misfires.
Yes. Worn or fouled spark plugs are one of the most common causes.
It may clear temporarily if the problem goes away, but it will usually return until the cause is fixed.
Only for short distances with caution. If the engine is shaking badly, stalling, or flashing the check engine light, stop driving and diagnose it right away.
No. It can also be caused by vacuum leaks, fuel pressure problems, sensor faults, or engine mechanical problems.
