1993 190E 2.6 CA smog failure again.... Help!

I took the car in for a CA smog test today with high hopes of an easy pass, due to a new cat and o2 sensor in 10/2010. What a disappointment... I failed and my numbers where worse than my pre-cat O2 sensor replacement. I have put 5098 miles on this car in a year and a half... I am about ready to take it to the junkyard, but probably won't because it drives great.

Below are my test scores from today and from when the Cat and O2 sensor were done...

4/27/12 test//

15 mph test..


%CO 14.01
%O2 0.1%
HC ppm 86/146
CO% 0.50/0.21%
NO ppm 697/636

25 mph test//

CO% 14.5
O2% 0.0
HC(PPM) 51/73
CO% 0.48/0.18
NO ppm 724/295

My test results after I had the CAT and O2 sensor replaced 17 months and 5098 miles ago are here..

15 mph test..
%CO2 MEAS 14.4, %O2 0.0, HC Max 86 test 8, CO% 0.50 max/ 0.00 test, NO(ppm) max 697 test 5

25 mph test..
%CO2 MEAS 14.9 %O2 0.0 HC Max 51 test 12, CO% 0.48 max/0.01 test, NO(ppm)max 724/test 5.

I should have taken the "baby benz" for a freeway blast before the smog.. I know... where did I screw up ?
