What causes a P0300 engine to misfire at idle?
This problem can be caused by a faulty spark plug, malfunctioning ignition coil or ignition module, a plugged or restricted fuel injector or an internal mechanical problem. The problem we are seeing with this engine is the misfire on a warmed up motor, only at idle. If you press the gas pedal just a little, the fault goes away.
What causes rough idle when accelerating a car?
I repeated this several times to make sure and having seen this specific symptom so many times before (where the rough idle is only present at idle and goes away when you accelerate the car), I had the feeling that one of 2 things were causing the problem: Low compression in one cylinder (or several).
Can a 2.2L engine misfire at idle?
Above idle, at faster engine RPM, there is no time for the cylinder to leak, so no engine misfire. The repair for this particular engine misfire is to replace the cylinder head and bad valves. This aluminum head is not repairable, so replacement is required. Again, this problem is specific to the 2005 through 2009 2.2L and 2.4L.
What causes low compression on Check Engine light P0300?
Low total compression can be caused by worn piston rings, incorrect valve timing, or valve and seat problems. Depending on the condition, this test may not show any abnormal readings. In this case, the compression on one cylinder is a little low. Squirting a little motor oil in the cylinder and running the test again shows no improvement.
What is the code for an engine misfire?
But this particular problem is with a computer trouble code P0300. This is a general engine misfire. For a particular cylinder, the code would be P0301, P0302, P0303 or P0304, as the last number refers to which cylinder is misfiring. On a scan tool we can actually watch the cylinder misfire.

What does it mean when cylinder 1 misfire?
The P0301 code means that cylinder 1 has a misfire and isn’t burning fuel properly. Bearing in mind that you need air, fuel and spark for combustion, the cause of a P0301 code could come from a few different sources. In any event, a P0301 code is serious and shouldn’t be put off.
What are the symptoms of spark plug p0301?
