Hello I've posted before on here asking for miss fire help. I have a 2002 Forester s, and if I remember right the code is p0302 for miss fire in cylinder 2. It only seems to miss fire after the engine has started to warm up and it's really noticable at idle. I've replaced plug wires, plugs, and the coil, as well as replacing the pcv. I have also checked the grounds coming off the battery and cleaned them up. I've taken it to a shop where they tested for vacuum leaks, they moved the plugs and plug wires around, and did a compression test, and the miss fire never moved. The mechanic said the car had compression but told me its a mechanical miss fire. He said there is something wrong with the camshaft or valve. But wouldn't that show up in the compression test? And on top of that it was going to to cost 2200 to remove the head and check it out. What do I do? And do you guys have any advice, I don't know anymore and I'm running out of ideas.
and a little more information about my car it has 148 thousand miles, k&n high flow filter, full exhaust tsudo 2.5 rs uel headers and high flow mid pipe as well as the tsudo 2.5rs catback.
