hey guys what do you think. I just swapped in a b16 into my 95 civic cx. hooked everything up pulled the neg battery cable to clear the codes. now before i even started it I checked the codes to see if they were cleared and it is giving my a code (one flash). Is my ecu that I got with the motor shot or did the code not clear. What s up with this.

 

o2 sensor is bad or unplugged

 

a slow flash or quick flash?

probably a wiring issue or somthing. you could always try a different ecu.
