This is the same replythat I gave to your other post.

Is it backfiring through the intake, and has there been anything done prior to this happening? It could be several things, low fuel pressure, wrong firing order, water in the distributor cap, flat cam lobe(s), clogged exhaust, timing chain/gears, distributor gear, etc.
