whats the code? check the wiring to the crank sensor, check your grounds.

guess i misunderstood you?

sounds like the ignition module is bad to me.

older cars dont usually throw that many codes, ignition module included.

Also check your mass air flow sensor. My car did the same thing as when the cps goes bad, but I 'm sure it's the maf. Also def. check the wiring going to the cps. You figured since the car is OBD2 it would show you the code right away to bad it just doesn't work like that. Also does the tcs go off when you have problems the would be caused by the cps.
