Also at lunch today the check engine light went out on its own. At times my afr are perfect idling at 13.9 then all of a sudden just fall on its face down to 16-17. I unplugged the maf and it did not change the way it was missing???

I am also goin to ohm out the injectors this evening as well.

The easiest way is to swap it out with another Supra. I agree this is a possibility. One of my Supra buddies did have a MAF go bad.

Do you have the TSRM? I know it's a few bucks, but it's money well-spent that will pay itself back over and over again. The MAF test procedure and thousands of other useful procedures are detailed in it.
