Vehicle Specs:
2006 Ford F 1-50 SLT 4WD 4.6 liter 2valve Automatin trans. 83000 miles with original factory spark plugs
I want to change the spark plugs and have purchased a repair manual.
The fuel rail is above the coils which are on each plug making it look difficult and a real chanllange. I CANT BELIEVE FORD WOULD DESIGN SUCH A SUPID SET-UP TO SIMPLY CHANGE PLUGS.
PLEASE SEND HELP AND ANY TIPS ON CHANGING THE PLUGS....HOPEFULLY WITHOUT REMOVING THE FUEL RAIL
