Running Rough Still...

I'm having this issue myself right now. The coil hits the side of the engine bay wall before I can angle it enough to get it out. It's not hitting a hose/pipe/part that can be removed. It's literally the metal on the side of the bay. I'll figure it out, but in the mean time I'm running new plugs/coils in 1-7 and old (unknown age - from prior owner) in #8. Weekend project...

I personally changed all 8 plugs and coils, I do agree that cylinder 8 was a pita to change the plug. Good luck with #8 though

Sat for years bought a month ago was my understanding

^ Thanks.

Really want to confirm he has stock plugs.

The oil in the plug wells is a bummer, if true. $$$ to fix. OP, did you do plugs or a shop???

Hey guys, sorry for going ghost for a while but I did change the stock plugs. I replaced them with OEM type Bosch plugs. When I took it to the shop, they replaced a couple plugs with different ones... not sure the brand off the top of my head. The only thing that is stock still are the fuel injectors. I always get 93 octane when I am fueling up, so a previous owner must've gotten bad gas before me. Also, the X5 sat on a lot for a few years before I purchased it about 3 years ago.

The boot side of the coil should have some flexibility and of course for the removal you could cut the rubber part: see if the new one has more flexibility to ease install. Look on YouTube for same engine/chassis combination to see what others have done.

It wouldn't surprise me if PO skipped #8 when they couldn't remove the coil.

I got both the coil and plug for #8 out, this is when I saw the oil all over the plug. Not sure if the shop I took it to got it out but I would hope they got it out.
