what is your ignition timing set at...it should be 15 degrees. I failed my smog test because my timing was off which messed all the number up. After i changed the timing back to 15 deg. it changed all the numbers and i passed. Also make sure you run your car for a while before the smog test to heat up your cat which helps, and when you get to the smog station leave your car running to keep it hot. DAMN CA EMMISIONS ARE TOO STRICT
