No issues that I know of.

I took the nuts off, lifted the coil pack out, and replaced the plug.

Pull the three half inch bolts holding the rail to the head, and remove the
entire rail and spark plug connectors at once. If you can, remove the wire
connector that supplies the coil rail. I am never able to get them, so I
just flip the pack up and on top of the valve cover. Be sure to use
dielectric grease in the plug boots and anti seize on the plugs.

Well, I finally got the chance to change my plugs.
UHM....I should've done this a LONG time ago!
The plugs were actually in ok condition (as far as burning/etc..).
The gap was not measureable by my gap tool (the disc one not the
feeler gauge pack).
I'd have to say I had at least 1/4" gap where I'm supposed to have
35thou.

Anyways, managed to snap a plug when putting it in, so had to clean
and regap an old one but it works great!
Noticed a significant difference in my mileage (and haven't finished
the tank yet).

Shame on me!

cheers
