Your O2's are definitely overdue to be changed. The ported MAF is not helping; the tune you're running doesn't take into account the changes to the MAF therefore your air/fuel ratio is off.

so what do i do about the maf? find a new one at junk yard? o2's usually throw a code i thought

Change the plugs and wires have it scanned for codes and go from there
