The idle issue could be water in the fuel, bad plug wires or any number of things. You need to pull the seat and check for any stored trouble codes and go from there.

The AC issue could be a few things as well. A set of AC gauges will help you diagnose rhe system. With an ambient temp of 80 degrees outside, the low pressure should be around 40 psi and the high around 200 to 225. The hotter the outside temp is, the lower the low reading will be and the high will be a bit higher. I do not like anything over 250.

The line frosting could be caused by the expansion valve failing to turn the compressor off, and that is a big possibility. The AC boxes are prone to filling up with dead And rotting leaves, pine needles etc.

Good luck.
