    Re: How to pass CA smog????

    to test the egr lift hose going to top of egr from side of black plastic cylinder at idle and suck on it. engine should die. if it doesn't, clogged port in intake . I had that when I first bought mine in 2000. doubt if it is egr gasket. mine had a very slight tear in it and caused computer to pump out excess hydrocarbons at all times.

    my 2018 direct fit carb cat from rock auto for $250. must have been a close out. now $1400. although welded carb cat is $250.

    got these results. although I'm not in a Nox testing area
