Arrow 90 Bonneville 3.8 Code #34 MAF Wiring & Now #26

I have a 90 Bonneville and it is crapping out and stalling, Code 34 which is MAF wiring.
I have tried another computer, and another MAF.
Also got another MAF plug and wired it to 12V, ground, and ran a wire inside the car to the computer pin #10 to bypass the whole MAF wiring.
Still getting code #34.

Anyone had this problem before?

Thanks,
Dave

Power for the MAF comes rite off the fuse block, fuse #17.
Has a ground wire, and a yellow wire that runs through the harness to the computer.

Thanks,
Dave
