After reading through the symptons below, it appears that I am better
off replacing both ignition switch and igniter. I think I observed all
the symptons of a failing igniter listed below with the exception of
the car not restarting after the engine cuts out. My car starts
immediately which is a sympton of a failing ignition switch.  Is it
normal for these two components to go bad at the same time?

Ignition Switch:

Worn-out ignition contacts could
cause the engine to stall without warning. Although the
engine will restart in most cases, a vehicle that stalls
while driving increases the risk of a crash.

Igniter:

A bad igniter usually gives some lots of warning with bizarre symptoms.
Most commonly, the car will buck for a split second, like the engine
has just missed. At the same time, the tach will fall to zero. The tach
falling to zero as the engine loses power will definitively confirm
that the igniter is going south, so watch carefully if your car seems
to momentarily lose power. In most cases of igniter failure, the Check
Engine light does not come on with a Code 15, which is Honda's code for
igniter problems.

You may eventually experience shuddering just before the car dies for
good. Usually the car simply dies outright with little warning, and
refuses to restart, even once it cools down. There have been reports of
the car restarting once cool, so the igniter can be confused with a bad
Main Relay or coil. Observing symptoms is critical to diagnosis,
especially with regard to the tach.
