Check the fuse that supplies power to the O2 sensor heaters (#6 in the underhood box, on some years). But that fuse also supplies power to things like the EEC solenoid and EGR solenoid, to those codes would have shown up to. That would possibly point to bad grounds at the sensors.
this thing hasn't run like it should since I purchased it
