Well, I finally passed.
I put on a new dist. cap, rotor, O2 sensor, 31" tall tires with 4.88s
Here are my numbers test 3:
set Timing = 10* (was 12*)
set Idle = 800 rpm (was 1100)
15 mph (1828 rpm)
CO2 - 14.4%
O2 - 0.2%
HC - 7ppm (127max)
CO - 0.02% (0.78max)
NO - 146ppm (1031max)
25 mph (2888 rpm)
CO2 - 14.5%
O2 - 0.0%
HC - 13ppm (108max)
CO - 0.07% (0.99max)
NO - 107ppm (891max)
What a difference!!!!!!!!!!!!
I still have the original CAT and I did not want to replace it because I wanted to find the real problem instead of just covering it up.
Thanks for all the suggestions and info.
Now I have to see if the ECU will turn off the EGR VSV when it gets up to temp. I just pulled the wire from the ECU harness connector so the VSV would always be off and the EGR would always be on.
