5.4L timing.

Does anyone have a picture or diagram for setting the timing on a 2004 5.4L?

(((the engine was rebuilt...runs like a champ over 1500rpm's...but when idling it idles rough almost like a vacuum leak (cant find any)...any suggestions?)))

If the timing was off it would run worse over 1500rpm [unless you have a 3 valve witha cam phaser acting up]'. Check your IAC.

all codes point to a mis on cyl #4. i checked voltages at the c.o.p and the injector and it is the same as all the others. so its either cop or an injector. do the injectors typically go bad on these engines? its a 2.V

On a 5.4 2V 9xs out 10 its the COP. Switch the COP to another cylinder and see if the code moves to that cylinder.
