car died, ecu codes 12, 13, and 21

[slow40]

First off, thank you for trying to help. Here's my problem. I have a 91 kade. manual transmission, auto ecu. One morning last week, I got up to run an errand and noticed my car ran rough. It seemed to have lost very noticeable power, almost like i lost a valve. I ran a compression test, 150 all across the board. I searched, seen a few problems with my similar symptoms and tried replacing the coolant temp sensor with one i had laying around, nothing changed. then I tried unhooking the maf and then it got better. So I figured i would clean the maf. cleaned it with maf cleaner and tried it again, now it won't hardly run at all. I tried it with the maf hooked up and unhooked, exact same results. I know that the ecu is supposed to flip over to limp mode to at least let the car idle with the maf unhooked, whats the deal? also, before it went completely bad, just running rough, when I would try to give it gas, it would bog unless i gave it very light throttle, if I gave it medium throttle, it would bog lightly, heavy throttle, bog until it stalled. PLEASE HELP ME!

no help? no love? oh well, put some good gas in it and replaced my cts and seems to be almost perfect. might have been bad gas or something?
