I could also get it to backfire by "foot on the pedal" acceleration/shifting like you'd get when merging into highway traffic and then letting off the throttle...
Do you have a backfiring problem?

When I first bought the car it had nasty backfire when decelerating. The flanges connecting the header to the side pipes were leaking. The backfiring went away after I replaced gaskets and bolts. The last few times I drove the car it would backfire when accelerating and decelerating That's what led me to check plugs.
