Default Engine Codes finally pulled

I have been having trouble with my ICM. Since the problems which I hope now are solved, I pulled these codes.....H51 and H42. Am I doing this right? I thought it was a differant procedure last time I checked codes. Any way, My engine light seems to pop on when I hit the gas and then shuts off when I let off. Very weird and annoying. Any help would be great !

Try this link.

According to one of the posters H42 = DTC #42: Ignition Control Circuit Shorted

H51 = DTC #51: EEPROM Programming Error.

Could have faulty wiring..

This is 94-96 specific.

Here is a list of codes:
