Help, SR running odd

Alright well I have been having issues with my SR recently. The computer isnt throwing any codes, I have spark in all coils, injectors tested good, TPS tested good, MAF tested ok. Compression is good. And I tore my engine harness apart and put it back together. I was having this issue before I ripped my harness out.

When I start my car, my AFR starts out at 14.8 then slowly goes to full rich. Then I start to give it throttle under load and it leans out fully. And if I give it a little more throttle, it goes rich again then back to lean with full throttle.

I am able to pull my MAF plug off and rev it to redline which I dont believe I should be able to. I think its supposed to go into a safety mode where it limits the revs to 2500RPMs. I know my MAF wiring is ok because I just had my harness apart and did point to point testing on the whole thing.

when the engine has reached normal operating temperatures, it still runs like ****. But if I turn the ignition key to off then restart it, the car will run perfect sometimes. I am completely dumbfounded to this problem. Would an O2 sensor cause this?

Is my computer bad? Any suggestions would be great.

I am currently testing this. I dont think this is my problem though because I am getting spark in all cylinders. just want to eliminate it as a possible problem.
