heres a rundown 96 civic hatch, b16a2 swap to a obd1 p28. i have 2 chips for this one with o2 disabled(using this i dont get any codes) and one with o2 enabled(code 43) my issue is i want to run the o2 but i get the code 43 ive tried two universal o2's both bosch one from auto zone and the other from oreilys. also bought the o2 extension tube. could it be those universal sensors just suck? i dont think it has anything to do with the fuel system because i only get the code when i use the o2 chip and sensor. maybe im wrong. or do i need to extend the o2 even further away from the header?
