Spark Plugs on 2005 Ford Expedition
I have a 2005 Ford Expedition (230,000 miles). Spark plugs have never
been changed. It started skipping. Went to Auto Zone and had diagnostic
done. there is a misfire on #6.
Took to mechanic to have all spark plugs replaced and probably coil pack on
#6. He called be back and recommended only replace #6 and coil pack
since that is the problem. Said it would cost me too much extra if spark
plugs broke when they were removing them.
Should the spark plugs not be replaced at this time? Would it not cost be
extra labor every time I had to replace another spark plug?
