From time to time now, I'm noticing that car is backfiring... Firing off loud .45 Cal type shots.. What can be causing that? One guy said because I have a 70ML throttle body, but I'm still running speed density. Said that too much air is flowing in, or something to that aspect.. I'm also running long tube headers and a H pipe with no cats.. First time it happenned it scared the crap out of me.. Suggestions, Reasons??
