What is the easiest way to change the rear driver side park plugs 2 from back

 

The word easy doesn't go along with changing those two. The biggest pain in the rear is getting the coil packs off the driver side 2 rear-most plugs. There is a metal fuel line that runs over top the coils that's gives you less than an inch of room to get a socket or wrench in there to remove the coil. I had to un-attach that fuel line just so I could move it a fraction of an inch to get a small socket or wrench over the coil bolt. Not a fun job at all.

 

I jut wanted to keep my fuel line a sealed unit

 

Get a 7mm 1/4 socket with a swivel built into the socket. Have telescoping magnet handy to grab the bolts. Its the easiest way to do it without pulling the rails.

 

Pull the fuel rails. It's 4 bolts and two tugs. The 10 or 15 minutes it takes will save you 2 hours of fighting them. If they come apart, put some oil on them and pop them back into place. It's that easy.

 

I agree with this. I wish I had done this BEFORE I spent the 2 hours fighting with a swivel and socket.
