Spark Plug Coil Removal 2004XJR
Started on passenger side to replace spark plugs. Figured the one furthest forward would be the easiest. Unplugged wiring; removed screw from coil. Coil assembly slides up and down very nicely; however, the shock absorber well prevents the coil from coming out.
I have turned the coil assembly every which way imaginable, darn thing still doesn't have clearance.
Thanks for your help.

Thanks!!
With the difficulty getting a car in for service in the Seattle area & the delays in having the service completed(not to mention the cost), etc., I could not keep this car that I like so much were it not for the help received on this site!
Hence, I am very grateful for all your help over the last 13 years!
Will be travelling for the next couple of weeks; so, will get back to this project in May. I'm sure there will be more questions.
Have a great Easter!

Last 2 on Right Side When Facing Engine?
Okay, back in town & thanks to the excellent help from you fellows, have replaced all except rear two on right side when facing the engine. The swivel & extensions recommended are the ticket!
I loosened the clip holding the fuel & vacuum lines; however, the grey one doesn't seem to move much.
The next to the last one on the right side(7?) seems to be blocked by the grey line (fuel line?). I can move the line, but not enough to get the coil out. Not knowing how much force I can apply before damaging the hose, I'm reluctant to apply too much.
Any hints on getting #7?
# 8, while I haven't done it yet, doesn't look to be as difficult.

You have to remove the inboard panel that houses the master cylinder. See this link:

Zazzy's tip will certainly help, but I've replaced the plugs on several supercharged and normally aspirated X350s, including our '04 XJR, and I haven't ever had to do that. I've always been able to just wiggle and rotate and contort the coil and eventually get it out with minimal movement of those lines. I'm sure I've had to bend the rubber boot on the coil somewhat while extracting it and again while reinstalling it.
Zazzy, what year and model is your car? Just curious to know it may be different in some way from the cars I've worked on.
That next-to-last cylinder on your right when facing the engine is number 6. All the odd-numbered cylinders are in the bank on your left when facing the engine (cylinder 1 is at the front), and all the even-numbered cylinders are in the bank on your right.
Cheers,
Don

It's a 2004 XJR. I've seen photos of other XJRs and mine is different. Don't know why. I tried every way possible to remove the COP without having to remove that clip and move the lines (short of breaking the COP in two).
