DOHC ZC Flooding! burning to rich. need help
Hey, my 1990 crx dx has a ZC motor swap, and its still in the shop because for some reason its smoking BAD. Everytime you push the gas it moves then stops then moves. The smoke that is coming out is VERY rich, and when i say smokes it comes out in HUGE black SMOKE BOMBS(You cant even see out the window! Its gas not oil.). The code was saying the o2 sensor is bad, we replaced that and its not helping. I have also read that the Teg ECU's make the ZC run rich, but that rich? So in overall for some reason the car is geting flooded. Someone please help me it would be very helpfull! thanks
Things we have Replaced:
-o2 Sensor
-TW sensor
Things we have Replaced:

Its not your head gasket. A bad head gasket causes white smoke. Most likely its your ECU. I had this happen to me before. The ecu had a short in it and the injectors were going full blast at all times. Pull the spark plugs out and check to see if the combustion chambers are really wet. The best thing to do is try another ecu.
