My first and WAY overdue tune-up was a success, just wanted to say thanks for all the info I have found from all on this forum.
I changed 15/16 of the plugs on my 07 hemi, and cleaned the throttle body. I ended up buying the magnetic swivel 5/8” sparkplug wrench from auto-zone. It worked like a charm for all but the one plug directly under the brake booster (my opinion it is still a great tool for 10 bucks). I will have to end up getting a regular plug socket and some small extensions to get that one plug. But I got the cylinders in the very back so once I get the right tools, it shouldn't be too hard to get to it.
From joining this forum I have learned a ton and now know that my plugs were killing my gas mileage and my truck wasn’t running super smooth. I had 103k miles on my stock plugs. The gaps in the old plugs were all around .065 and new ones I put in were set to .044. My throttle body didn’t come out spotless by any means, but I did get a lot of the old crud out.
I went back with a small amount of anti-seize on all new threads and very lightly coated the inside of the coil boots with dielectric grease applied with a q-tip.
I think I have gained about 2 mpgs and engine runs a lot lot lot smoother.
A couple things that I learned that may help someone else with an 07:
The passenger's side was tougher than driver's side for me. In order to get to the rear coils and plugs I had to do 2 things. First I had to remove the 2 vacuum type lines out of their clamps (green arrows) and rest them ontop of the clamp. Second, I had to tie up this huge electrical conduit of wires (red arrow). Once I did this I didn't have too much of an issue getting my wrench back there (you can actually see it).
And as far as the throttle body goes, slide the red part of the electrical connector all the way to the LEFT. This will allow you to slide off the connector. I also used a walmart bag and some tape to help prevent any brake cleaner from getting into the electrical parts of the TB.
Hope this can help somebody else.
