    today i failed emissions, the guy said car was running rich to much fuel.

    I assume you're not throwing any codes?

    Well if you have any codes, that's probably why your burning rich. Essentially the check engine light or your ecu throwing codes has something to do with the emissions of the car and means its polluting the atmosphere, and it'll change the air fuel ratio to compensate for whatever isn't right, and generally burn rich. If you notice your gas mileage isn't good anymore, this would also be a reason why.

    If it hasn't been tuned in a while I would change spark plugs, cap, rotor and wires if they look shitty.

    Clean the fuel injectors. That's most likely the problem.

    How bad did it fail?

    Depending upon how bad it failed, will tell you how bad things are. If it's been running real rich for an extended period of time, the cat could be burned out. That will make emissions worse. You should have noticed gas mileage worsening if that's the case.

    Post up the smog dyno numbers please.

    Too much fuel? Vise grips on the feed line. Less fuel.

    Bad fuel pressure regulator? What kind of fuel pressure you have? What about an injector that is sticking open? Or not closing all the way.
