    Sold my 4runner 2 years ago. Bought it back non running with a bad injector and no CAT. Installed a CAT, rebuilt denso injectors, plugs, ported vacuum switch, power steering pump with new vacuum switch and several new vacuum
    Lines. Started truck and fuel was literally dumping out of exhaust. Also found fuel in vacuum line out of fuel pressure regulator. Replaced regulator. Now fuel is still in exhaust and was leaking out of return line on regulator. Also runs very rough and obviously extremely rich. Not sure where to go now. Any ideas would be loved. Thanks ahead.

    Where did you get the "Denso" injectors? Sounds like one is stuck open.

    GB Rebulders. Ordered them through CarId. That’s what I was thinking but could stuck injector dump a gallon of gas in the exhaust in about 1 minute. Seems like a lot of fuel to go through that tiny injector. Gonna start testing the injectors either way. Thank you
