What about if I JUST filled my refridgerant and converted to 134A since all the R12? leaked out...I fixed the leak and converted, but the ac isn't Ice cold like it should be. Just moderately cool. Any ideas?

If it's been exposed to air. IE the system opened then the dryer/receiver should be replaced, and vaccuumed down. Although I've done it and not vacced it.

Another thing I've been told (so take that for what it's worth) is that using 134a is not a pound-for-pound replacement for R12. It may take the manifold gauges and some 'tweaking' of the amount installed to get the coldest possible output.
But, as above, if you didn't replace the drier and/or have the system fully vacuumed out first, it also probably won't work right.sigpic

Ive seen r12 systems that had 'leaked' still recover a little bit of refrigerant. I also recommend ester oil on anything that didnt come with r134a from the factory.Old and improved:
