cylinder 8 plug change I have cylinder 8 miss fire got new plugs and wires how exactly do i get to cylinder 8? The only way you could get to it is from the bottom by the looks of it. Would just like to know what tools i will need?
I remove the coil packs,then get it from the top. Your other alternative is get under the car and remove from the bottom with a short handle rachet. I have long tube headers
so going from the bottom is out of the question.

I don't disconnect any coils, rails, ect. I am able to get #8 out in 10 minutes by going under the car, with stock exhaust. Headers have made no difference. There's a 1" socket extension you'll want if you don't have it already.

Once that back bolt is out the first time, you can leave it off. Then future rail removal takes only a minute or two. At that point it's much easier to do it from the top IMO. I never do it from the bottom.
All cars i work on only get two bolts on the bracket on from then on.. Takes less than a minute to remove packs..
Always top.. Helps me if i get on top of battery. Bigger guys cant do that.

I have done it from the top twice without removing the coils. I have like a tiny extension that has a little swivel. I stick the socket on the plug first, then put the ratchet on. It's not hard. Maybe my tools are just the right size. My hands usually have scratches on them after though. Lol But I seem to be able to get a lot of bolts some people can't. Maybe it's cause I've been turning wrenches my whole life.

On my '98 there is no rail, so I do that one from the top with all the coils in place. It's harder than the '02 with the rail removed, but not as hard as the '02 would be with the rail in place.

I did mine from the top only part that killed me was my spark plug socket got stuck on the plug because the acdelco plugs are wider and the rubber in the socket got stuck. So it took another 10 mins to get the dang socket off after tightening the plug.

I get to that plug from the top (both with and without the rail removed), but what takes the time is working 'blind', not being able to see what I'm doing, and I'm ALWAYS worried about cross-threading that plug opening's threads because of that. 
Also, isn't that the cylinder which always runs the leanest, due to the way the fuel rail/injectors are configured??
