I would take it back to the place that inspected it, did they do anything to it?

Did the vacuum lines get hooked back up or do you have a cracked one?. Almost sounds like the distributor is not advancing correctly when under a load.

Unless the gap is WAY off it shouldn't cause a backfire. Idle's smooth I assume? As Ray said, maybe timing or vacuum lines or timing.
