Ok i got a b18 put in my civic woopdedo blah blah blah anyway it was in for about a year and never could get rid of the cel it said the secondary o2 sensor was bad so i put about 5 new ones in and never did fix the problem so i tested the wiring and it was good so i just said screw it and ran a signal wire from the o2 to the ecu and bam no cel to this day but every since then it has a skip to it now but i un hook the o2 and it runs fine till i get a cel, does anyone have any suggestions??? please help. or is there anyway to bypass the secondary o2?
