Alright, I'm ripped hehe 1st Failed:

HC: 1.95 Limit: 2.00
CO: 12.71 Limit: 30.00
NOX: 6.07 Limit: 3.00

2nd Failed (today):
HC: 3.12 Limit: 2.00
CO: 19.87 Limit: 30.00
NOX: 7.38 Limit: 3.00

The 1st attempt my smog pump was removed. 2nd attempt I put it on, and it failed even worse.

What's the fuggin deal? EGR Valve? Cat????????? I'm going to go ahead and do the O2 sensor, and I'm making an appointment as we speak for a high-flow cat. DAMMIT!!

 

The high HCs usually mean a rich condition. Try a new O² and have the engine at full temperature for the test.

A functioning EGR can seriously lower NOx, but you'll still need a good cat.
