First remove the negative battery cable. Relieve the fuel pressure from the fuel injection assembly. You must remove the fuel injection assembly to get the coils out. The assembly is anchored to the manifold by 2 screws on each side of the motor. Once you get the screws off you can move the assembly up or away enough to get to the coils. I would remove the wiring from the injectors. (BE CAREFUL NOT TO MIX UP THE WIRES. DO ONE AT A TIME) The coils are anchored to the manifold by one bolt on each coil. (7mm) Gently pull the coil up and disconnect the wires. From there you should be able to put a spark plug socket into the hole and unscrew the plugs.
