To remove the spark plugs on a 2003 Buick with a 3800 engine, first, ensure the engine is cool and disconnect the battery. Remove any necessary engine covers and locate the spark plugs, which are usually found on the engine block. Use a spark plug socket and ratchet to carefully unscrew each spark plug, turning counterclockwise. Once removed, inspect the condition of the plugs and replace them if needed, making sure to gap the new plugs correctly before installation.
