ZC motor backfires

Just got done with my ZC swap and now its back firing really bad! I doubled check the whole dizzy wiring and crank angle sensor wiring. It all seems good. I solder the connections. I tried switching spark plugs, wires and cap. Nothing! I'm thinking either the dizzy(ignition coiL) is bad or the crank angle sensor. I'm leaning more towards the dizzy. Anyone got any tips? Also, I am supose to use a 89 integra dizzy correct? This is the black valve cover dohc zc motor from japan. I see the dizzys on ebay but they all say OBD-1. I'm using the PG7 ecu. So my car would be obd-0? Thanks guys, - Jim.
