Durango start issue

I have a 2000 SLT Durango, 5.9. I've been having a issue starting it for the past couple weeks. I've had the TPS (throttle position sensor) replaced, coolant position senor replaced, Fuel injection cleaned out, Plus has had a new battery in recent months. The Durango will start fine for several days then usually it's in the morning, I will start it, it will idle high then low then just die, so I try to restart it and it immediatly dies. So this morning I held my foot on the gas pedal for about a minute to keep it idling, when I let off it stayed on. My auto shop doesn't know what's wrong with it, there's no problem lights on, so diagnostic comes out normal. Does any know what this could be caused from?

Dirty idle air control valve maybe.

Where is the Idle air control valve? Is this something I can clean myself? if so, can you expalin how? Thanks

It's mounted to the side of the throttle body. You can take it out and clean it if you want. I would replace it already. It's a five year old truck.

When you go to buy a new one, you'll see exactly what it looks like, it will be easy for you to locate it. They're cheap.

What finally fixed this? As a courtesy, you should post fixes or attempted fixes. That's how we all learn.

thanks in advance
