Hi there,

On the BA falcon, check that the inlet manifold is not leaking, normally at the rear of the engine, gas backfire is often lean mixture or cross firing leads and as you have DFI this will not be a problem.

Note if yours is a late AU check that the leads are ok as well as any manifold vacuum leak.
