So i have a 97 4x4 5.4 it started running like crap and missing so i decided to change the coils and plugs i bought this truck used so it needed to be done and i didnt know what i was in for i pulled off all the coils and got to my first plug got it out with no prob the second one turns out already had the repair plug so it wasnt the usual 5/8 and got that out no problem then it came to the third on 5/8 /9/6 didnt work and neither did any metric sizes all the motor work on this truck seems to be done pretty half assed any thoughts or slotuions to figuring what its gonna take to get out or what size it might be idk thanks in advance

 

Use an air blower there might be dirt around it that's what happened with one of mine

 

That very well could be ill have to give that a try
