hey guys just a quick one sort of new to the ls1 world just came over from the import/turbo scene and thought id start doing a few little mods to my ute. so basically done the mcai all was good fitted up nicely took it for a spin all good. then went out for a longer drive and pulled up at a set of lights and noticed when in drive it had a small misfire while idling. i made sure EVERYTHING was clipped back together eg maf and sensor on air box and can not see anything else loose what so ever. the only thing to have changed is the air box has anyone had problems like this before or is it just my luck. i took it to my mechanic Monday afternoon and got it scanned but nothing came up. its going in on sat too be looked at but thought id see if anyone had any ideas. before the mcai the ute ran perfectly not a misfire or anything any help or info would be great. not sure if i've posted in the right section will see how i go cheers guys
