You need to disconnect the spark plug wire at each spark plug, twist the boots one-half turn before removing and pull only on the boot or use a tool designed for this purpose to remove the wire from each spark plug. Then disconnect the spark plug wire from the distributor, twist each spark plug boot 1/2 turn and pull only on the boot or use a tool designed for this purpose to remove the wires from the distributor.
