Default Keep blowing fuses, lost reverse, MAF and O2's. NOT a O2 grounding.

I am posting this for my buddy while he is at work. His car has started idleing rough and he lost reverse, his MAF and his O2's apparently. He had this problem before and it was due to O2's grounding out against the body due to how his hooker headers place them. Apparently it is not grounding there, but it keeps blowing the same fuse. Any other common problems this could be?

I have a feeling his wires further up on the O2 sensor wiring may have gotten on a header and burnt/grounded.

I had some of these issues. Turned out to be the O2 sim wires next to the tranny area. They were shorting out on the tranny itself when under load. Had to be the last thing I checked too....

He posted this for me... Another thing....

When I replace the fuse, it WILL NOT idle at all. I have to feather the pedal to keep it running. Fuse blows, and it idles "ok".
