my buddy has a 1990 RRC and he bought it from some guy in NY. I will admit the wiring is butchered and the check engine light is constantly on. It runs rich. We are thinking about making it carburated. Does anyone know if this is possible? I was also suggesting him to put a euro ECU in since they dont have 02 sensors over there. His 02 sensor wires are cut and the other one is missing.
