I have a 99 expedition with the 5.4. It just died and when starets wont idle or idles very rough. When giving gas it dies. I ahve relplaced the fuel filter. Any suggestions
there are a wide range of possibilities but the Idle air sensor on the upper intake plenum could be the problem.
Coil Pac for SURE!! I've been the NOT so proud Owner of a 2003 Expidition and That has been the only oain in my A@@!! Check with an OBD Code Reader. You can buy it at Auto Zone for $60.00. Tells which one is malfunctioning. Good Luck! Sabrina
