Sounds to me like you may have carb issues. I had the same codes before i had my carb rebuilt last December, turns out the TPS was bad and a worn throttle shaft caused a vacuum leak causing my lean condition. The worn shaft is common to the q-jets. The carb rebuilt took care of those problems along with my unsteady idle.
If you are going to take the carb apart to replace the TPS, you might as well do a complete rebuild.
Also, check all the vacuum lines (and there are a lot of them), chances are they need replacing also.
