I'm going to replace my plugs and wires. I see that on the front, there'* a plastic rail or harness that guides/holds/organizes the front 3 plug wires. How do I remove that rail so that I can remove the wires from it, and then install the new ones?

Also, is there any trick to replacing the rear 3 plugs? I can reach them, but I wasn't sure if getting a socket wrench down there would be easy.

Any tips or information at all would be great. Thanks!

All you do for the front wires is pull them out if I remember correctly the rail itself slides onto some guides on the valvecover and the wires are just pushed in. Not to sure on the rear plugs I am about to find out tomorrow. I went for it and bought the AC Delco Iridium tipped plugs. I will let you know.

Slide a small flat bladed screw driver along the clasp of the retainer to release.
The one in the back are the same. You can route the wires if you have more retainers under the snout of the super charger instead of going over top.

Got it guys, thanks! I was making the wire-retainer much harder than it was.

You just have to reach for the rear plugs. No real tips that I can recommend.

Plugs, wires, and coils are now replaced. There was all kinds of carbon build-up on a couple of coil terminals. After the complete swap, Gracie fired right up. And no more misfire, either! Hopefully it STAYS that way.

A GM FWD V6 engine tipper would help a lot with the 00+ guys, Can be found for 20-40 bux online.

Whats an engine tipper?
If this is for rotating the engine forward like they can do with gp'* than no, the front engine mount on our cars will not allow this. And if you remove that mount the drivers side of the motor will drop?

No. If you remove the front mount, the engine will rotate nicely to the front and give prodigious access to the rear.

For the 00+ remove the bracket on the back that holds on the engine cover. This allows a lot more room to get your hand back down there to do the change. Be sure to use anti-sieze when you put your new plugs in and the next change will be much easier. I just did mine today in about 15 minutes (getting the hang of it .

I had a bit of a bad idle and stuttering up around 100mph. Turned out two of my plugs were gapped at .50 instead of .55 (not sure how this happened since i just regapped them when we didnt the springs).

I thought the plug gap is supposed to be .60 or is that only for the */C?

For 2000'*, (both N/A and SC) 0.060" is the right measurement. At least that'* what the GM Service Manual says.
