To replace the spark plugs on a 1993 Cadillac Deville 4.9, first, ensure the engine is cool and disconnect the negative battery cable. Remove the ignition coil and then the spark plug wires, labeling them for reinstallation. Use a spark plug socket and ratchet to unscrew the old plugs, then install the new plugs, ensuring they are properly gapped. Reattach the spark plug wires and ignition coil, and reconnect the battery cable.
if it is a v8 it has 8 spark plugs if its a v6 it has 6 spark plugs and ect
Spark plugs are easy to change. One disconnects the batter and spark plug cables, and removes the old spark plugs. Next a person puts in the new spark plugs, then reconnects spark plug cables and the battery.
A 97 Deville would be equipped with the Northstar V8 engine, therefore, it has 8 spark plugs.
