Stalling out 97 dodge 2500 5.9 gas

Your idle air bypass motor is bad or fouled with carbon deposits. Remove it and clean it with throttle body cleaner . If that don't work replace it

there is a sensor that will increase engine revs when turning at slow speed , i expect this is the issue, to check get the OBD codes read to confirm

Dirty air filter, dirty throttle body...try 2 bottles of gas line fuel injector cleaner...has your car been parked for awhile? Heet gas additive will work on any low gas tank sludge that you may have. Hope this helps.

run fault codes to find the sensor putting on the engine light.

Your problem might be a bad idle control motor. Good luck.

The choke function is not working on a cold engine.
1 clean throttle body and IAC motor air pathways.
2. Check for engine codes, you are looking for a code that relatws to the wngine temperature sensor.

A few things actually lol. How long since its last tune up? A dirty air filter, worn spark plugs and wires and cap and rotor can cause a poor idle and stalling. Not to mention a dirty fuel filter. The fuel filter is in the gas tank unfortunatlly :(
Try giving it a basic tune up " about 45 dollars" and see if that helps. Good luck.

Possible EGR valve sticking open.

its your idle control valve

Sounds like a bad IAC (idle air control valve/sensor) that controls your idle when going from throttle to idle. If bad your idle will act crazy and can cause stalls easily. Pretty sure that's it.
