Use FIXD to scan your vehicle to verify P0300 is the only code present. If other codes are present, they must be addressed first. Check for loose connectors at the ignition coils or for damaged wiring. Look for loose engine ground wires as well.
What causes a P0300 multiple cylinder misfire detected code?
First, if you’re getting a P0300 Random/Multiple Cylinder Misfire Detected code, that would indicate a universal problem that applies to all cylinders. In that case, start by checking fuel supply issues like poor fuel pressure caused by a bad pump, restricted fuel filter, or a defective fuel pressure regulator.
What does a P0300 code on a spark plug mean?
Usually, if there is a problem with a spark plug or a separate ignition coil, we will get a trouble code on that specific cylinder. The P0300 code is telling us that there are misfires on several cylinders, which is much often more an air-fuel mixture causing it.

Is there a quick fix for the P0300 code?
To fix the P0300 code, you need to diagnose which cylinder the misfires occur and what is causing the misfires. There is no quick fix to the P0300 code. What causes code P0300? The P0300 code is most often caused by a faulty spark plug, ignition coils, low fuel pressure, or a faulty fuel injector.
What does the P0300 cylinder misfire code mean?
P0300 Trouble Code – Cylinder Misfire. What Does the P0300 Code Mean? The P0300 Trouble Code indicates that one or more engine cylinder is misfiring. If the last digit of the trouble code is not zero, for example, the code generated is P0302, the number 2 suggests that the cylinder number 2 is misfiring.
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 causes sparkplugs to fail with P0300 code?
