Interested, but have no good ideas.
I would assume the computer is reading the lean mixture from the O2 sensor, and is therefore trying to richen as much as possible. Are you sure it's a backfire, or a misfire or afterfire (gas exploding in a hot exhaust?)
Also remember, instead of too much air (vacuum leak) it could be not enough fuel- low pump pressure, clogged fuel filter, bad injector or wiring to it.
Good luck
