i was headed to school and a integra that was painted dark green w/ sparkles, looked kindof cool if it was a chick driveing it.... anyways i was just trying to get away from him rideing my ***, and i pushed down a little bit on the gas and started misfireing like usual, well i got up to like 4k and then took my foot off the gas and shifted and it made a huge POP , i'm assumeing it backfired, it was wickid ****ing loud so i just pulled over to the slow lane and let the kid go by, then i pulled over, i figured it could'v also been a tire or something.. but ya... i just baught brand new plugs, wires, fuel filter, pump, and throttle body cleaner, gunna do all that this weekend and hopfully get rid of the fricken problem forever!!
