Unhappy P0456 with idle issues and starting issues

I have the P0456 code coming up and have replaced the gas cap. I have an intermittent idle issue. At rest, my jeep idles up and down and will die out. I also been having issues starting my jeep. It will roll over the engine a few times and then sounds like the starter is spinning without turning the engine. The jeep runs fine at high speeds. Don't know where to turn. Any help?

could be a bad starter if it catches then spins freely.
idle problem start cleaning the idle air control valve first.
