How do you change the back spark plugs on 2002 Monte Carlo SS?

To change the back spark plugs on a 2002 Monte Carlo SS, first ensure the engine is cool and disconnect the negative battery cable. Remove any components obstructing access to the back spark plugs, such as the intake manifold or ignition coils, depending on the engine configuration. Use a spark plug socket and ratchet to carefully remove the old spark plugs, then install the new ones, ensuring they are properly gapped. Reassemble any removed components and reconnect the battery cable.
