    I have to say that I don't know what to say. I am completely unfamiliar with lambda. And I am baffled as to why your NOX is still high

    what ive replaced so far:
    spark plugs (champion oem)-fuel pressure regulator-air filter-oil change-oxygen sensor-map sensor-engine coolant temp sensor-ran berryman b12 chemtool fuel system cleaner-checked ccv valve for clog (clear)-replaced ALL vacuum hoses.
    according to test results CAT is doing its job. as for the jeep its runs GREAT, no overheating at all, has power and has NO problems...
    while changing spark plugs i noticed the combustion chambers were RELLY carboned up bad. using the berrymans b12 helped clear alot but theres still some in there. (currently running another tank of treatment for carbon-could be the suspect??) im absolutely at loss now.. i hoping the fuel treatment will help with carbon in combustion chambers and that it will help bring nox down.

    Then I would say you probably have carbon still in the combustion chamber. One thing you can do to get rid of it is trickle water down the intake at about 200 rpm. As much as it will take and not die. The steam loosens it up

    UPDATE: FINALLY PASSED SMOG!!- 5MONTHS LATER-6 SMOG TESTS FAILURES!!
    ok so in my post i put down everything i did to help my NOX lower for smog test.. did alot of repairs and even though they didnt contribute to much to lower NOX i know i wont have to replace those parts for a while!! in the end, it ended up being my INJECTORS.. they were really dirty. i guess a bit clogged or carbon build up the mechanic said. after he cleaned my injectors my NOX went from 1100ppm to 102ppm passing!

    Glad to hear you got her taken care of and through inspection... At least now you know you got good parts in there for the ones you did change out.. and now you should def get better gas mileage with the parts changed and the injectors being cleaned!!

    yea definetly drives smoother and noticeably better! with only 70k im kinda suprised it was carboned up that bad but then again i only drive it to work which is only 7mins away from where i live and i believe short trips contributes to carbon build up. the best part is driving again without looking in my mirrors for police to pull me over for expired tags!!
    thanks again fellas!!
