I also posted this in the integra section.

After failing the first time i took the car in (it registered 1.67 g/mi of HC, 10.51 g/mi CO, and 3.71 g/mi of NOx) i change the spark plugs, wires, dist cap and rotor, and O2 sensor. I also reset the ecu. Now i just took it in and it did WAY worse. Its now running 5.87 g/mi of HC, 36.95 g/mi of CO, and 16.855 g/mi of NOx.

What the hell is going on? What could be causing it to run so rich?

 

BUMP.

I have a smsp high flow cat on it that i bought in spring and it only has about 2k on it. Im thinking i should just throw the hole stock exhaust back on.

yeah that would prolly be a good start. was the car warmed up?

 

Yah, it was running for a good 20-25 minutes before it got tested, then ran for another 15-20 minutes on their tester.
