Can I save a yellow leaf?

No, once a leaf has turned fully yellow, it will not turn green again. It is best to snip it off to help the plant focus energy on new growth.

Does too much sun cause yellowing?

Usually not, as this plant loves full sun. However, if the soil dries out completely in the sun, the leaves will yellow from dehydration.
