My car is having an issue idling. At first I thought it might be the battery or some other electrical issue but I can't manage to figure the issue out. I can only manage to get the engine to turn over upon giving it gas and keeping my foot on the gas to keep the engine idling. I attempted to let up on the gas from after having let it run for about 10mins and it would stall immediately. I believe it to be the Idle Air control motor but it seems to be functioning properly. Currently I am about out of ideas with the many issues that could be originating from the throttle body and simply am about to give up.

Clean out the idle air control valve and the EGR valve then test the throttle position and manifold absolute pressure sensor
