How should you inspect a spark plug for issues such as bridged gaps, deposit build-up, and signs of pre-ignition on 2005 Mercury Mariner?

Inspect the spark plug for bridged gaps and deposit build-up from oil or carbon fouling. Clean as needed and check for oil or carbon fouling signs. Ensure normal burning with light tan deposits. Look for pre-ignition or overheating signs, and replace spark plugs if necessary. Check for fused deposits from sudden acceleration.
