Hello All My 21 VVC-R powered has a missfire! I discovered it after its long hibernation, and I don't think it was there when i did the oil change etc. It gets worst when the engine is hot up to 3000 rpm after the engine pulls like a train and I think it can be felt when the engine is revving in neutral. Is there a guide somewhere, on how to trouble shoot a miss-fire? Cheers Jack
