ignition casette and intermittent check engine light

My 2001 95 Aero has an intermittent check engine light. Its on for a
few starts then off for a few...repeat. I
had the codes read and the ignition cassette was in the log. The DI
has been replaced at least once in 97K
miles so this is not the original. The last time the car died
without any notice. Is there any chance that this
could be caused by worn or bad spark plug?

It is possible but ... From my 9000 back then ... the regulation was
to change sparking plugs before a new cassette was fitted as a sparking
plug could cause the cassette to go bad.

Sorry if I am not of much help.
