How do you change spark plugs on a 2005 Ford E 350 5.4 gas?
== == Remove the air filter and the doghouse. then you have to
remove the fuel rail use a 8mm wrench to remove once bolts out
gently putt up. Next remove coil(had one small bolt sorry cant
remember size) pull coil straight up to remove then with a 5/8
sparkplug socket some extensions swivels remove plug. Do your self
a favor any place some never-size on the threads. Ford Fleet
