Ok, took it in for emissions test today and got back some really bad readings...not sure whats wrong. Anyone got any ideas?

(reading)/(allowed)

25/25 test
HC ppm = 1652/114
CO% = 1.11/0.63
NO ppm = 1795/796

50/15 test
HC ppm = 1184/117
CO% = 0.91/0.65
NO ppm = 1482/879


I have no idea and really need some help here, I got to get this thing on the road.

For starters, how about a COMPLETE ignition tune up from cap and rotor to plug wires and plugs. Then have the injectors professionally cleaned for example on the rails like I do with 3M injector cleaner. Then consider replacing the O2s and lastly, the cat converter.

If that doesn't do it, Ill come to Georgia and help LOL

Whats done to the car

Just a high flow cat and K&N intake. I just did a full tune up on the car maybe 2 months ago (plugs, wires, new opti, new coil), although I am aware of the "reliability" of the opti so I am sure that could be the culprit. Gonna take a look at the O2 sensors. The funny thing is that even with the emissions missing that badly, I am not throwing any codes...

With all 3 tests that far over the limits, it sounds like the cat is deceased.
