88 CRX B18B1 Trowing o2 content code

[Dbordelo83]

I recently did a B18B1 swap on my 88 CRX SI. The swap went well, well as well as any swap can go anyway, When i first started driving it the car was throwing a fuel supply code I then replaced the o2 sensor and the code went away, But now it is throwing a code 1 which is an oxygen content code. The car runs great but i was wondering what could cause that code to throw with a new o2 sensor. Could the wiring to the 4 wire 02 sensor be mixed up. Any help would be appriciated thanks

Well checked continuity from sensor to ecu. Everything checked out. Switched two black wires b/c ive heard they can be easily confused. Ill start it up tomorow and see what happens. Does anyone know if that code could be from using my stock SI air box with the B18?
