From a cali smog tech....CO that low, you prolly had O2 in there, and you need to look at the co2 also...tells you how well the cats working. WIth CO that low and nox that high...your car is lean. Period....espically with bumbers that high still on nox after a new cat, adn everything else youve done. Yes, the chrysler ign boxes are a problem..plugging the vacuum line doesnt make it run like crap, and yes it will lower nox and HC. Your amm is prolly dirty....not uncommon. Ive had more than one car where everythign is new, everything seems fine and it runs ok. uncleanable dirty AMM...glad you squeaked it by.....but just an FYI

Ive got a thread in articles about smog failures

%CO2 was 13.1 at 15 mph & 25 mph.
%o2 was 2.1 and 2.1 at 15 mph & 25 mph.

CO(%) was 0.05 and 0.03 at 15 mph & 25 mph.

I'm just stoked it passed. I last had a Volvo in 2004 when my 3rd kid was born. We couldn't fit 3 car seats in the back of the 740 - bye bye 740, hello Mini-Van. Now my wife wants a Volvo again so we're just about ready to start looking.

Ya youve got an exhaust leak or the car is running lean...but a pass is a pass...plain and simple
