Well i took it to get a smog pretest and everything is set. The only probalem is my CO% is at 3-4 percent. What do u guys suggust to bring that down. Thanks

 

i dont know..but I gotta SMOG in August..

 

Are you completely stock or do you have mods?

If you are stock, replace your O2 sensor and spark plugs. Make sure everything else is working properly (like the air pump) and try it again. If you fail again, time for some denatured alcohol.

 

well i have arpump and main cat and precat on. I believe all of them are running right. I might need to chang spark plugs and o2 sensors. I also put some alcohal when i did the test. My numbers drsticlally improve from 110 hc ppm to 20 hc ppm at idle. Anymore suggustions.

 

i have a pfc tuned for smog also

 

California smog rules must suck......
