Failed ca smog due to high nox for one of the speed test. Nox was 440/74x and max is 48x. Have the deletes so I put oem cats back and retarded timing. Funny thing is last time my nox was very low under 50ppm. Forgot to change oil so I will do that after finishing this tank of fuel with cleaner. Might do a boost leak test. Plugs are from 2011 with 40k miles, and I will change them before next test.
So I ran ecutalk and TPS was at .42 so I adhested that to .46v. Does tps make a difference? Also noticed there are two O2 readings. One fluctuated between .2-.9v and other one 'RH V' was pretty steady at .2v. It does move if I rev but steady move. Is this normal?
