Changing Spark Plugs ??

Hi All,
Well just turned over 80k and thought it was time to drop in a new set of plugs. Just doesn't seem to have all the power it used to. All the posts around about twisting off the coil bolts has me concerned about attemping this. Any advise? :screwy:
1. Did it when the engines cold.
2. Twist out slow.
3. ??

Coat with plenty of anti-seize on reassembly.
AC plugs 41-103. right.

Was thinking of hosing up the TB next. Maybe this will help with the power. One change at a time though.

Thanks

'02 TB 4.2 I6

Always check the newest ac spark plug book for plug specs.
I show AC Delco 41-965 set at .043 gap
Factory gap was at .050

On the platiumn plugs do not attempt to reset the gap.
If plug gap and tip is not set and centered right pitch them back and get ones that are.

When changing plugs check air and fuel filters and pc valve.

And do not hose around on the TB.
It will not help and may make matters go the other way.

Also go easy on the anti seize, the threads are your ground here.

I have replaced two sets now, 02 LTZ with 201,550+ on the ticker. The last two plugs that are under the windshield are a real bear but can be changed. For me, it worked better taking the rubber plug out of the spark plug socket until it was completely loose, then putting the rubber back in to grab minus the extention bar. Starting the new plug in I would leave the rubber in, but then take it out before tighten the new plug. I notice now that I have some oil laying on the plugs, most likely due to a gasket leaking.
