How do you change spark plug and wires on a 1994 Oldsmobile royal 88?

Change one plug at a time. Start by removing the "boot" covering the spark plug. Leave wire connected on other end. Use ratchet with "spark plug" attachment. Remove old plug, insert new plug. Attach new wire. Follow old wire to the correct connection. Remove old wire. Connect new wire. Continue until all plugs and wires are changed.
