Re: Emission Test Failed due to high HC

If u wanna check the O2, use a volt meter. If if pules between .2 and .9 volts, than it`s working correctly. But if it`s going way above .9, than it`s more than likely shot. He could also have an exhaust valve that doesn`t close all the way, or a leaky injector.
