I hope everyone's thanksgiving day was a happy and joyful experience.

OK, I'm having trouble decoding the check engine light on a NON-OBDII 1992 Ford Escort. I have the STI pin grounded and when I KEY ON I get a bunch of flashes from the check engine light, problem is I don't know how to interpret the flashes.

Take a lookie at the video and see what you think....

What I saw was 1-1-1, 1-1-1, 1, 157, 157

I don't know what's up with the preamble. I think the actual code starts @ 1:04.

157: (Running,Mem) Mass Air Flow signal is/was low or grounded – MAF

*A 0.5 second flash (separator code) 9 [C], followed by a 6-9 second pause [9] [D] indicates the start of trouble code output for memorized faults [9] [El.

*Each trouble code is displayed twice. Firstly for present faults followed by those for memorized

OH!... I thought they were going to be two digit codes.. 157 makes perfect sense now. Thanks!
