ok guys need some real help. i had my computer sent out and tuned to my mods because i am not near any shops. i plugged everything in and it fired up and idled great. i only had shorty headers on so i did not rev it at all. i saw some flames shot every once and a while. after fabbing my exhaust i put it on and fired it up. it started great but every minute or so it would back fired really bad and just exploded my driver side muffler. i noticed one of the injectors on the driver side had bad o-ring. so i replaced, unplugged the battery for a couple of days to reset it and fired it up again. it idled ok but as soon as i revved it, it back fired real bad again, these back fires are ear popping i mean bad. any suggestions?
