Plug Change
Thanks to Kozal01's writeup, I was able to successfully change my plugs without breaking any. I really think if I'd tried to wrench 'em out by hand, I would have broken some. The air impact method worked great! I was able to do it with a small pancake compressor and inexpensive air gun. I turned the output on the compressor to 60 psi and went to work following Kozal01's write-up as best I could.
Some of the plugs took an extra shot of penetrating oil... and I had to let the compressor catch up... but I was eventually able to get them all out.
My truck is a '06 F150 KR with 77,530 miles on it. The truck had started bucking on light acceleration between 40 and 50 mph. Changing the spark plugs cleared that right up.
Oh yeah... I also ran a heavy concentration of Seafoam a day or two before I tackled the job. I added a can to a little over a 1/4 tank.
