dirty throttle body, 99% sure on this

costs about 5 bucks and an hour to fix

ETA: could be what mojo said but this describes exactly what my truck was doing, if there isn't a hole thats the problem

the IAC solenoid is the compute controllled device that allows air to enter the engine around the throttle body plate when closed. It keeps the engine running when the compressor kicks on and when shifted into drive. It's possible the IAC is dirty but my money is on the PCV 90degree elbow. A simple spray with carb cleaner back there with the motor running is all that's needed to diagnose.
