How to tune up a 2003 ford f150 5.4 supercrew need directions
There is not really a whole lot to tune ups on these models.remove each coil,one at a time,by removing the hold down bolts.You will have to twist and pull to remove.The boot,if in good condition when removed,can be reused,if not replace as one or two,but if one is bad,replace all of them would be the better choice.As you do this,do them one at a time,unscrew the spark plug,and install the new one,checking the gap as you go(some spark plugs will have no gap to set).Replace the air filter,and the pcv valve,and the fuel filter.That`s it.No adjustments are required,and your ready.If this was at all helpful,please let us know,thank you.
