I have 91 Hatch that I swapped A JDM B16 Obd0,PR3 ecu into, Had bogging problems, read your thread about switching primary and secondary O2 wires, that took care of the problem, runs great! Thanks, Now after driving for about 10 miles the CEL comes on. Read the code, Secondary O2 sensor. Replaced the sensor with new one, CEL still comes on. Any thoughts?
