Misfire problem unknown?? runs code P0300, multiple cylinder misfire detected. where should i look for my problem, no egr, new plugs and wires, not water in the gas. i dont know where else to look. any help will be nice. if you have any ideas post up. help me out thanks
Could be a coil or injector as well. Is it a dead miss or just random? Do you have access to a scanner to see what cylinder # it is on? If not you can unplug injectors one-by-one to see which one it is.
You can set a random misfire code when 1 cylinder is a dead miss. That p0300 code doesn't mean it is really just random. It will make a big difference diagnosing your problem if you can figure out if it is 1 cylinder missing or all of them across the board.
