Same as above
I'm recieving error code 1 from my car. it comes up once in a while but has been doing it more and more lately. haynes says to check and replace the o2 sensor if nessisary but this is the second new o2 i've used. I have a vx but swapped in the d16z6. still using the vx wiring harness. wired the o2 sensor using a write-up i found on honda-swap.com and rechecked it so many times. what else could be causing the problem?
