My truck dies when I turn airconditioner on, an if already on it will idle up an down couple of times the die. It takes a while before it will start an acts like it wants to die when I put it in reverse. what could this be? I just put brand new fuel pump and filter on it and two air flow sensors.

Hi blueeyes197882, Welcome to 2carpros and TY for the donation.

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