Default SES light blinking steadily

I know this has been covered before but...
started my car (90') and it ran fine. SES light came in for a few seconds without flashing and then began flashing. When under throttle, it would stay on. When decelerating or out of throttle completely, it would go out. Then it started flashing steadily, on, off, on , off, etc. No sequence, just off and on constantly. I would have to wonder if it has to do with air intake? Again it ran fine the half hour I drove it. I'm going to pull the car by jumping the ALDL.
Any ideas or anyone have this problem before?

I know that a misfire condition will blink the sys light, but I think you would feel the engine missing. Possibly a bad knock sensor setting the misfire code? Codes should tell you.
