my A/C drops out when I am stopped or idling. It comes back cold when I start driving. What needs to be replaced and can I do it myself?

A/C systems are very complex and take special training and equipment to properly diagnose and repair. You should take it to a repair shop and have them look at it. Probably not the answer you're looking for, but without a basic understanding of A/C systems, you can do more harm then good.
