First and foremost, any relocation of the factory O2 sensors and Cat's CANNOT be certified as 50 state legal, and it is why we do not advertise them as such.
Your knowledge of the use of O2 sensors in the exhaust is flawed in that most computer control vehicle system will utilize the O2 sensors for fuel trimming purposes, this goes with race cars as well.
Our standard arm headers do come with High flow CATS to allow for a check engine free environment, which is what you have. What you do not have is emissions readiness which CAN be remedied by one of the above listed checks and by performing the readiness list listed above.
What we do advertise is a check engine light free environment. That we delivered, your vehicles emissions readiness is a result of an issue with your specific vehicle. Our calibrations do NOT mess with that, otherwise we would NOT have received our CARB EO number on out 2007-2011 system, which IS advertised as 50 state legal.
All that said we do understand your frustrations and are trying everything we can to address your vehicles specific issues.
Yes, my knowledge of O-2 need is far from complete so that is a fair enough statement.
Also, yes, Maybe I said "emissions legal" above but I did actually mean is MIL free which in my state of NH is essentially emissions legal.
I appreciate you understanding on my frustrations. They mainly revolve around the length of time it has taken to resolve the issue. This is of course partially my fault as I have been in and out of the country for the last 16 months.
I have however thoroughly gone through the vacuum system, exhaust system and replaced the one Component you guys recommended which was the part from an SRT Neon, I forget the exact component. I have also ran numerous different programs from Diablo. The last one as I recall makes the Jeep run fantastic but still has the "not ready state".
Anyway, I will returning from China for a couple weeks later this week and if I could resolve this it would be great.
I will try the other things you recommend, probably starting with plugs and wires then O-2's.
Do you make a recommendation on specific plus, wires, coil?
rear o2's fail more often or front or does it matter? I obviously want to spend the least amount possible so any advice is appreciated.
