Where are a 1997 Cadillac ElDorado spark plugs?

There should be 4 on each side of the block, follow the wires.... to change them you will need a socket with a long extension and a pair of needle nose pliers to gently remove the plug from the deep dark hole.... Make sure to only use GM wires and plugs or else they will not last... I was advised by a GM tech, of this problem. first though, remove the plastic cover on top of the engine, 4 nuts
