Could be a faulty spark plug or spark plug wire.
To change the spark plugs in a Chevy Celebrity: 1. Give the spark plug boot a twist to free it up from the spark plug, then pull on the boot to remove the spark plug wire from the spark plug. 2. Use a 5/8" spark plug socket with an extension and ratchet or breaker bar to loosen then remove the spark plug. 3. Set the gap on the new plug to .045" then screw it back into the spark plug hole in the head. Tighten the spark plug and replace the spark plug wire. I change the spark plugs one at a time to keep from getting the spark plug wires on the wrong spark plug.
