Hesitant Startup, Low Idling and Random Stalling 2000 Camaro

What is your question?

My car seems to like to idle very low at red lights, it takes a long time to start, sometimes needing the accelerator pressed to start up and after waiting 2 or more minutes stopped at a light, if I turn right or sometimes even going straight it likes to stall out. I've been told several different options but my dad seems adamant that its my Throttle Body, he unplugged a sensor from the Throttle Body and it idled fine, when he plugged it back in it resumed the low idle.
