spark plug replacement

[marcom13]

Hey all you wrench heads--30 years ago I could rebuild an engine from top to bottom. Today, I'm lucky I can change the oil but I don't like not doing for myself soooo- How the hell do I get the plug wire loose to get at the spark plugs. What is on the top of the plugs and can I ruin anything while changing the plugs? Also, should I used anti-sieze goop on the new plugs? I'm still not getting very good mileage so I figure the plugs are next. I just used BG44K in my tank will see if this helps. Thanks for your help past and hopefully future. This group rocks--big time

What engine do you have?

[marcom13]

Brian, I have the 3.4L v-6 engine with a 5 spd manual tranny also equiped with Trd package, electric locker, 4x4.
I hope this info helps, I'm only getting 15 mpg and its getting to where I can't afford to drive it. Thanks for any help I can get.
