Emissions Help!?

[bowtiekid]

Ok, I pulled the engine harness out of my 95 and went through it very throughly*sp*? and found quite a few frayed wires and connections. I also fixed the EWP switch and wired that a bit neatly.

So after that and replacing the PCV valve and hose these are my new test results:

My Car: HC: 1.76 Limit: .80
My Car: CO PASS http://www.ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif
My Car: NOX: 4.19 Limit: 2.00

Throwing no codes, only thing is the ABS light comes on but thats it, and it only does it at the testing place for some reason. SO what should be my next step??????

Thanks in advance!

if you have not done plugs/plug wires and change oil, do that. Make sure when you are testing your cat is very hot. Sometimes fuel filters help with nox

With those hc numbers i would look at a bad o2 clean plugs and decarbon the intake. The nox look at the egr for correct fuction but thta number should come down some when the hc comes down.
