Anybody know how to do a tune-up on 2003 F-150 4.6?
Need to change the plugs, spark plugs, & coilpacks on a 2003 F-150 4.6. The damn fuel rails are over everything. Anybody ever done this? I'm just gonna jump in and see what I can do, but I was wanting to know if there was any easy how-to's or don't do's. Thanks.
if you have a good wobble socket 7mm, you can do it without having
to mess with the fuel rail. The hardest one is #5,
Take your time and do one at a time, remove the coil. then remove the
plug replace it and go on to the next.
well on the expeditions with rear ac #4 is the hardest #5 is easy and who takes the fuel rails out? 7mm wobble and u get the cop's out with no problem (#7 has the fuel reg. next to get u push the injector towards the rear and if u need unplug the injector to gain access). I have done like 10 5.4L and 6 4.6L tune ups not to mention all the cop's replacements i have done. with an 1/4 air ratchet u should be able to knock them out in 45mins.
