Doofus,
Great video, I just watched it. I did almost everything they showed except for the cleaner into the spark plug wells. I used the same type of socket wrench they used in the video and it took a lot of effort to break my plugs free. Most of them also squealed as I turned them loose. I worked the plugs back and forth between tightening and loosening as I removed them. The plugs had quite a bit of resistance for the first 1/3 to half of turning them out. To sum things up this plug change was a PITA and I kept thinking about how much easier and quicker it was to change plugs on my old Chevy 350.

99f350sd,
Tell you what, I'll sell you my 8 stock injectors for half the cost of new. They've only got 43,200 miles on them so you will be set for a long time. IF you have an issue you can clean them and still come out money ahead. I'll anxiously wait for your reply!
