Curious what a 7 flash diagnostic code indicates. I have the factory manual and it does not indicate what 7 flashes is. In fact there are no single digit flash codes in the manual. They start at 12. There were no spaces between flashes. It was a steady uniform 7 flash, 5 seconds then repeat. Any help is appreciated.
 
On a 94' the only code with a seven (7) in it is 71, EGR (this is a common one).

I'd recommend pulling the ECU fuse to reset the check engine light and then see if the code comes back.
