hey guys im reading all over and some people are saying any cam just about will throw a po300 code .is this true.and that the misfire perameters need tro be set higher.im not feeling it alot and i feel it could be the cam.its just alittle shaky in gear at idle,wen it pops the code.i do feel it alittle more with a/c on.like a bad plug.but i could be looking too hard.ya know .some are saying that low idle will cause it.turn up the idle 500 rpm could fix it?it does do it wen the idle comes down.aaaalllleen what do ya think bud?
