Got this from JTIS:
The right-hand cylinders are numbered 5,3,1 and the left-hand cylinders are numbered 6,4,2 when viewed from the rear of the engine.The ignition system consists of an ignition coil located on each individual cylinder and each individual spark plug. The ignition timing can now be adjusted more rapidly and independently.The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is converted by the powertrain control module (PCM). This digital signal is then used to position the closing time of the primary circuit of the ignition coil. The effective range for ignition timing control is increased to the fact that there are no rotating parts.On the basis of engine speed and load inputs, the powertrain control module determines the ignition timing. This function also takes other inputs into consideration such as engine temperature, throttle position, knock control, cam position, traction control and electronic transmission control inputs.This ignition system enables the customer to drive the vehicle home if a coil or coil wiring failure occurs. In the event of a wiring failure between the powertrain control module and the coil, the coil will fail instead of the coil fuse blowing, which will allow the remaining coils to continue to function and the engine to limp home.
Based on this you will probably have to remove the intake manifold to get to the #2 coil and spark plug.
Recommend you get the JTIS either from the christo message or order it on line. It has instructions as well as diagrams. It is written for technicians so keep that in mind.

You can try this thread, however, there may be some issues the moderators are resolving and it may not be operational.
