4.6 Question About Throttle Body Vacume

Discussion in 'SN95 4.6L Mustang Tech' started by dannydoo, Jul 19, 2013.

  1. This is a 04 grand marquis 4.6l same motor

    The throtttle body has 2 vacume lines on it,1 is about 1/2 inch closest to the end of t/b
    It goes into some type of selenoid on the pass side of fire wall w/a quick connect and turns into hard plastic tubing right there. Other wise its 1/2 inch rubber

    I cant find any dealer or autopart store to name that part so I cant order i t,

    Its def a vacume line,its cracked. Not a antifreeze line.

  2. Look up the thread "2003 gt engine failure" see if that's the same part.
  3. It might be handy to mention the model year of your Mustang. If this is a 96-98 MY, my vote is the EVAP purge line and the part by the firewall is the EVAP purge sensor.

    Otherwise, pictures would help.
