How do I find out what is causing my misfire?

To find the cause of a misfire, start with checking for trouble codes in the onboard diagnostics system with a scan tool. The codes may not pinpoint a specific part, but they should identify the cylinder or cylinders that are misfiring as well as other systems that aren’t functioning properly.

Is P0300 expensive to fix?

The most common repair is to change the spark plugs and spark plug wires (if used), or what we sometimes call a tune up. Here the price can start out at $150 for many four cylinders and range upwards of $700 for six cylinders and eight cylinders.

What happens if you drive with a P0300 code?

Driving a vehicle with a P0300 engine code can be a gamble. While the code indicates a misfire, the severity and implications can vary based on the underlying cause. In some cases, it might be a minor issue like a bad spark plug, which, while not ideal, won’t immediately jeopardize your vehicle.

The OBD II system detects misfires on most vehicles by monitoring variations in the speed of the crankshaft through the crankshaft position sensor. A single misfire will cause a subtle change in the speed of the crank.

What is the most common cause of a code P0300?

The most common cause for a P0300 code to appear is worn spark plugs. Other causes include a weak ignition coil, contaminated fuel injectors, excessive carbon build-up on the intake valves or low fuel pressure due to a faulty fuel pump. In rare cases, a vacuum leak or an exhaust leak can be the source of the problem.
