Hey! Lean is mean!
I've not had to replace a MAP sensor... and it was my TPS that was bad that caused my backfire! It was just a bad one... and would get heated up and break down. Started crapping out -- then would be fine -- then would momentarily loose the throttle... When it finally went it caused a backfire in a drive thru at a McDonalds! It scared the woman behind me so bad she backed out of there and left!
I had to have the poor old Nomad towed back to the shed after that one.
