Need some advice for next steps
98 2500 5.9l v8 4x4
im having an interesting idle problem. When the engine is cold, the idle after a few minutes will sound like it’s bogging down and going to die but the RPM’s never change, I can give it some gas and it’ll go back to idling how it’s supposed to.
I’ve changed the IAC valve, and the TPS and cleaned the throttle body.

Disconnect negative terminal at battery. Turn on headlights, turn off headlights, reconnect battery, turn ignition to "On" (don't start it yet.) Count to 10. Don't touch ANYTHING. Start the truck. PCM should figger out idle fairly quickly.
