No special tools required. Plug socket and short extension. The Spark Plug may be rusted in place. Try some rust penetrating spray and let is soak in for a few minutes. Break the spark plug loose. Many times the porcelain portion of the plug may break upon removal. Make sure all pieces are removed before removing the spark plug from the cylinder head to prevent and pieces from falling into the engine. You did not mention how old the Spark Plugs are. I recommend replacing all of the Spark Plugs and Ignition wires. One last note. Do Not turn your distributor. Rotating distributor will have no effect on ignition timing. All ignition timing values are controlled by powertrain control module (PCM) . If your rotate the distributor you will un-sync the Crankshaft and Camshaft Position sensors causing many engine and driveability issues.
