Getting a code 33, wondering if the inline fuse for the fuel pump in the two wire weather pack should also power the MAF? I currently do not have both wires connected. Didn't think it was necessary since there was only one wire on the other side.

If the maf was not seated properly in the intake would it pull in extra air and cause that code?

On another note, I replaced the power relay and the code disappeared, car ran great, until I turned it off then back on. Then it was weird again. Still a code 33.

Wiring for the fuse in question...

 

So you can see the two wires coming through here, one has the 25a fuse and the other isn't connected, would this cause my problem? How do i know if it's positive or negative?
