Backfiring??

My car has started back firing after I hold WOT for a little while and than back off and get back on the gas. What is causing it to do this?

Re: Backfiring??

I had backfiring when I was running really rich. This was because of a bad ignition box and o2 sensor problems. It was so rich though you could smell it at idle and it would pop at idle as well.
