Try these out brother
Natalie, our 4.2 engine only likes 1 sparkplug. AC Delco 41-103. This Iridium plug comes pre-gapped, to near the specs Mike posted. Don't try and gap these particular plugs yourself, easy to ruin them.
One more thing, don't buy these on e-bay or Amazon, too many fakes. Even happened to me. Authentic AC Delco is not shiny, and has 3 small dots on top where coil goes.

SOURCE: battery removal on a 2004 GMC Envoy
The battery is on the right side behind the fuse box. You need a metric set to undo the 3 screws. Theres one that attaches to the body, one to the bar that goes along the top, and theres one on the left side below the vacuum hose and air induction. After you've taken out those three, you should lift the whole thing out(battery and shroud) together. It's hard to take the shroud off before you lift the battery out. After that, you have to pry the shoud off the battery. The two terminals in the back make it hard. Then just go to any auto parts store and they'll give you a new one.
