Possibly a bad belt? Maybe your belt is slipping when the AC goes on. Inspect the AC compressor pulley and see what it looks like.

sounds like a bad IAC valve, you can try cleaning it and see if that helps. when was the last time you changed your PCV valve and did you buy Ford or aftermarket?

ok then I would go-to a Ford dealer and get a new PCV valve as they should be replaced every 30k
