2015 Dodge Cara R/t 3.5l

Low side 80 psi at engine off with engine temp 195. Low side pressure 35ish at idle engine temp 195. Car idle at 3k low side pressure drops to 15+/- engine temp 195.

Rear air warm, passenger air warm, drivers side coolest.

Low on gas? Opinions needed. What should low pressure read at idle?

 

with your gauges,hi & low sides connected, turn air on,rev engine,see if low side goes to 0,if so,the Expansion Valve is defective, if system is working correctly, hi side will be bout 175 - 180, low side, 30-35 at an idle, have to know what the hi side is doing
