How do you change the spark plugs in a 92 GMC Sierra 2500?

Pull the spark plug wires off the spark plugs. Remove the spark plugs with a spark plug socket. Install the new spark plugs and put the spark plug wires back on. I recomend replacing the spark plug wires as well. If replacing them, just remember that the new wires are hooked up the same ways that the old ones came off.
