I have to keep my foot on the gas at all times or it dies. I can drive 30-40 miles before the idle kicks in

First eliminate the possibility of any vacuum leaks. Once that is ruled out, you may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
