Ford Mustang: Ford stalls, wont idle

    Ford stalls, wont idle

    Howdy:

    I have a 85 LTD CV, that stalls and wont idle. Its TBI's
    vacuum-activated, throttle positioner's plunger, can be extended about
    1/8" with a MityVac. Is this 1/8" a correct setting? Or, should it
    move further?

    Can anyone tell me how to test the solenoid that controls the vacuum to
    the positioner? The solenoid has two wires attached to it. Where does
    the signal(s) that controls the solenoid, originate?

    I haven't any manuals or troubleshooting charts for this problem, but
    I'm hoping that some readers here, have encountered this problem, and
    are willing to share their solutions.

    Thanks
    TD

    Sounds like the diaphragm in your Carb is shot. VERY common problem.

    Check out the 5.0/5.8 Tech Forum on the Crown Vic website. GREAT bunch of
    folks there! VERY knowledgeable as well.

    Carb? No, it's fuel injected. The thingy that's supposed to kick (or
    stop) the throttle lever, doesn't move more than a fraction of an inch,
    with applied vacuum. Ergo, no idle.

    Does anyone know of a DIY limp-home trick, to get around this
    malfunction?

    Be sure to check and clean the EGR valve along with the spacer ports. This
    was/is a problem and will cause a stall along with a rough idle.

    Good Luck

    Howdy:

    Our CV is back on the road. The old, idle speed screw trick, should
    keep it running until the new throttle positioner arrives.
