Thanks in advance.
I recently changed the spark plugs on my 2005 Ford 500 with the 3.0L engine. These are the problems I had when removing everything. The toughest thing was getting the EGR off. I don't know how the heck you remove the huge bolt on the bottom of the EGR valve and I don't know how you can even get a wrench in there. I just took the plunger out that goes into the intake manifold. The two or three bolts(I forgot) are a b*tch to get to and even worse to reinstall. The other thing I didn't know, just maybe out of lack of experience, was the the upper and lower intake are sandwiched together. The 10mm bolts hold the lower intake onto the engine and the torx bolts hold the upper to the lower. I removed the 10mm bolts and pulled the whole plastic upper and lower intake off together. I don't know if this was any easier, but thats what I did. The problem I ran into was I ordered the wrong seals. The seals between the upper and lower are oval shaped and the seals between the engine and the lower are a T shape, but still kinda oval. If you can imagine a circle like a T.
I just followed the directions on the Ford service manual. The spark plugs were easy to remove. I didn't have any trouble. You just remove the single bolt on the Coil over ignition module and pop it off. My car had 130k on it and they didn't look that bad.
