And if that switch acts up you get a "timing issue". Just say I'm right and move on.

no you have a no or intermittent loss of spark not a randomly time changing one. Do i need to break out the tech data?

Intermittent loss of spark is a god damned timing issue. Break out what ever you want.

boy are you thinking wrong. when one describes a timing issue it is known and meant to be that the timing is out of adjustment from expected parameters not randomly not firing as it should be. random no fires is different from a timing in degrees wondering from its expected position under any given operating condition of sensor data and so forth.
Ignition Control (IC) The VCM software controls all of the IC and Bypass functions. This reduces the number of circuits outside of the controller and ultimately reduces the possibility for shorts or opens in those circuits that could result in driveability complaints or DTCs.
The ignition system initiates combustion by providing a spark to ignite the compressed air and fuel mixture at the correct time. In order to provide an improved engine performance, fuel economy, and control of exhaust emissions, the Control Module controls the distributor spark advance (timing) with the Ignition Control (IC) system.
The ignition system uses a primary and secondary sub system in order to accomplish the timed spark distribution. The primary system consists of a low voltage trigger device which determines the base timing. This signal is modified by the Ignition Control Driver (ICD) Module. The signal travels to either or both the engine and transmission processor (Control Module) for base timing reference. Another signal is sent back to the Ignition Control Driver (ICD) Module, which has been adjusted by the Control Module (advanced or retarded) in order to trigger the coil, according to the requirements of the engine.
The secondary system consists of the ignition coil which has primary (low voltage) windings and secondary (high voltage) windings. The secondary side of the ignition coil generates a high voltage which high tension spark plug wires deliver to the spark plugs.
The Control Module controller now controls the Ignition Control (IC) and Bypass functions.
In order to properly control the ignition/combustion timing, the Control Module needs to know the following things:

n.
1. The regulation of occurrence, pace, or coordination to achieve a desired effect, as in music, the theater, athletics, or mechanics.
2. The synchronization of the sparking of the plugs with the movement of the pistons in an internal-combustion engine.
Listen to me, I didn't say a bad module is going to throw off the valve opening and closing events (ie timing). I am saying dropping random spark or late signals to fire said sparks will cause an issue (ie timing issue).
