Hi guys. I'm new here and thought I'd introduce myself. I bought my Ford Excursion Limited 6.0 in 02. She's an 03. She has serviced me well all these years. I'm having a problem with rough idle and missing now. I have replaced, within the last week, the ICP, FICM, and the IRP but still hasn't fixed my idle problem. It has the EGR delete kit that we done about 4 years ago. When I plug a scanner in, I get a "No communication". The cigarette lighter still works. Any idea what might cause this? Thanks in advance!
Thanks Stewart_H.
Even with power to the lighter are you sure that you have power to the port?
We can see if some of the people that have the early Ex like your will chime in
in the mean time I work on getting a no com diagnostics PDF put together for you.
Likely it will be latter Monday evening.
