What causes a P0300 to misfire on multiple cylinders?

Infrequent misfires are recorded but not tied to a particular cylinder, and on some platforms, this stores a P0300. Typically, any situation that isn’t tied to a particular cylinder but is causing misfires on several different cylinders is suspect. Fuel contamination would be one possibility.

What does the last number in p0302 mean?

The last number in these accompanying codes refers to the affected cylinder. A P0302, for example, indicates a misfire on a particular cylinder (in this example, cylinder 2). Cylinder number 2 would refer, not to the second cylinder in the firing order, but the cylinder numbered “2” in the arrangement of cylinders on the engine.

What is the code for a cylinder misfire?

For instance, if the misfire occurs on cylinder #4, the code indicating this will be P0304, where the “4” relates directly to the affected cylinder. Similarly, misfires that occur repeatedly on specific cylinders will set codes that end with the numbers of the misfiring cylinders as the last digit in the codes.

Keep in mind, however, that a faulty oxygen sensor is just one of many potential causes for the code.
