    cylinder misfire

    So ever since I got my protune 15 months ago, my car has been throwing an 0301 off and on. one day it will be on, then the next it won't be. now my AP is reading 0301 and 0304. However, I don't notice any drop in performance or hear any sounds. Could this be a problem with my tune, or is it something I should be really worried about?

    Thanks for the redirect! My only question is that this guy noticed/heard his car was misfiring; I haven't noticed anything out of the ordinary other than the CEL. Is it actually misfiring or is it just something funny with my tune that's causing it to throw?
