ok lets see 2days ago my gas light happen to come on so i went and filled up my tank well every since then the gas light...won't go off....then this morning knk numbers ranging from 2-30 and small backfire it wasn't constant but from what i can gather it happens everytime i go over 3,000rmp any clue to what may be the problem...i was gonna see about having the gas light reset and im kinda thinking that im getting the backfire and knk readings from possible bad fuel it was 93 from bp but there was alittle bit of 93 from base fuels mixed in...if you guys have an idea let me know
