In my expeirence, every time my car has failed it was the driver. do a search and see my old notes, then talk to the driver before he tests your car.

I think there is a vac tank or something that can be emptied out to help with passing the test. I read it somewhere...

did you try driving your car around first to let the cat warm up? dont let your car sit with the engine not running. make sure the engine is warm and has been on for at least 15 min.
