Well I pulled the old fugue regulator off and no gas came out of the return hose. So hopefully I'm thinking that's my rich culprit and why the vacuum line popped off was actually a good thing according to the smog guy. 1 Could this been a culprit of my EGR codes as well Because the computer was trying too hard to compensate?

Failed again Knox still too high but not as high as before. Is there a way to test nox before smog. Just put new o2 sensors in. And then I'm really lost what to do

Several things can cause high nox readings, bad egr, lots of carbon in the engine, an air leak after the maf causing the engine to run lean. Are the cats original?

Co2 is at 13.0, o2 is 1.6, hc is 18, co is .01, and no is 1120 ppm. The other low numbers say the cat is working

I just released when I changed the egr stuff and put new pigtails on the purge solenoid is a newer version oval plug. Was that wired the other way or will it even work? I did it one wire at a time with the cutting and soldering but I could have very well got that one wrong.

for a computer, try a JY. usually cheaper than repair, and 99% of the time they work...
