If you have a backfire problem then you best follow the flow sheet in the shop manual. My guess is you have blown a vacuum line with the backfires, under the plenum, check the MAP first. Do the vacuum pump test, an easy check to confirm anything leaking under the plenum.

I take it you don't have headers? I know with headers you may get backfiring unless you get a new upgraded chip from Marc Haibeck which eliminates the backfires.
