I just got through living your nightmaare...Being labled gross polluter in Cali is a kiss of death because ther are limited stations that can pass gross polluters That said, here is my path that included many wrong and expensive turns...

First advice--"replace the O2 sensor and you should be good to pass... maybe a new CAT..." Replaced CAT, O2 sensor, plugs, rotor and cap... Failed worse...

Second advise... "must need to clean your injectors and throttle body...I can do that for ya..."-- failed again

Third times a charm right..." what ya got here are defective electrical conections on your ingectors--- passed smog but failed visual as the check engine light came on

Fourth time---"you must have a short... may take a while to find it..." cleaned all conections from the wiring harness--- Failed cause I had 17" wheels that threw off the new Cali smog dyno

Fifth attempt--replaced stock wheels on rear for the test... Passed with flying colors...

Best of luck with your car... hope you do beter than I did... but now I am good for two years...

um, i think he was bsin you about limited stations not being able to pass gross polluters. i think its my cat, o2 sensor is less than 3 months old but keep the ideas coming guys

[droptopsilvia]

a CAT should solve it, I failed on everything but one I got my catco cat put on I passed in HC and CO but not NOx still trying to figure it out.
