It's not uncommon for pressure to build up in the fueltank.
You use gas, and the cap seals. Gas expands and contracts quite a lot when it heats up.

jig:
Your gas cap issue isnt the problem.When I undo my gas cap on a hot summer day it releases pressure from the tank.
As for your other concerns give us a little bit more info. i.e.:engine hot when the idle gets irratic?cold?
Idle 2 meaning 2K or 200?
5 meaning 5K or 500?
Do you have a stock engine or modded?mileage?
Help us help you sir.
