What is the best method of changing spark plugs and plug wires on a 1997 Chevrolet Malibu with a 3100 V-6 engine?

Answer

Gap the new plugs, look at how the wire is routed and pull only that plug's wire off, and swap out the old plug for the new one. Snug the spark plug down, then tighten it a 1/4 turn. You don't want them too tight. Once you've done a couple you'll be able to guess at the torque. Find the correct new wire by lining up the wire you just pulled and match up the lengths. Now route the new wire in the same or close to the same path you took it out in. Repeat the process for the other five plugs. Don't let the wires touch each other very much or they could crossfire. Removing the plug wires one at a time keeps you sane and makes it virtually impossible to mess up the firing order. Be patient, you don't want to break off the plugs in the head (major PITA getting them out, then) and there are some tight clearances. Easy once you get the hang of it.
