have you had the the engine codes pulled and reset?
and if so what are your engine codes?
i dont know of any car that will pass emissions test with the engine light on.
we cure your trouble that caused your engine light to come on and you will pass your test.
later

fill your muffler with SOS pads just before your test a wire coat hanger can remove them after the fact..

SOURCE: rough idle
well you need to hook it to a computer and determine if o2 sensors are working correctly and make sure enough fuel pressure
SOURCE: failed emissions....high nox
Sticking egr will raise everything except nox. Bad o2 bad cat hard to give an accurate diagnosis with out checking it

Based on what your write up says it would have to be a timing issue or Mass Air flow Sensor (MAF) .If your getting 20 HG's at idle steady there can't be a vacuum leak.Your a little on the rich side so its probably a dirty MAF.Try cleaning it first and see what you get . If that doesn't work then reset timing.
Keep me posted on this .
