Passed emissions & ?????

Well she finally passed, thanks for all of your help it was the O2 sensors and bad cats like you guys said.

NOX 0063 (Allowable 1378)
HC 0031 (Allowable 0180)
CO% .99 (Allowable 1.01)

What do you think of the readings and CO% is slow close to the allowable # is this ok or is there more problems down the road?

Your high CO (carbon monoxide) emissions are probably due to not enough air mixing with the fuel. Try a new air filter (or clean a K&N) and replace the PCV and screen. You may also have a leaking injector(s) or a bad sensor: (coolant, throttle position). At that close to the maximum you'll probably fail the next test so I would attempt to find and try to minimize the CO levels you're at now. A new air filter may do it.
