Thanks. But before I commit to a shop I'd rather investigate the issue myself. That's why I posted here--to try and get some insight into those codes and possible cures or diagnostic procedures I could do myself.

I have a friend coming over Friday and we are going to do a vacuum check. The other parts are probably due for replacement anyways.

Any other suggestions would be welcome.

Thanks!
