wont stay running
98 durango, 5.2 eng, 4wd.
When I started it today I had to keep engine speed up to keep running. As soon as I take foot off gas peddle the engine dies. Also no power and dies when placed in gear. Used obd 2 scanner but no codes. I can here fuel pump running and now I,m thinking its a problem with the IAC. Any help would be appricated.

First of all make sure your battery is good. Dodge is really weird about having a certain voltage on the battery or it will just die, unless you rev it up a little then the alternator will put out the correct voltage for the PCM.
Get the battery tested under load and clean out the IAC port and valve:
How to Clean the IAC Solenoid:
This is recommended at every Tune-Up to prevent excess carbon buildup on the IAC plunger. In some cases, you'll notice a slightly erratic idle quality. This is the first step in taking care of that problem. IAC = Intake Air Control (Solenoid).
1. Remove the Air Hat from the Throttle Body
2. Disconnect the sensor harness from the IAC Solenoid (Rear of Throttle Body)
3. Remove the two Torx-25 Screws
4. Remove the IAC Solenoid (Be careful not to lose the rubber O-Ring)
5. Spray some Carb/TB Cleaner in the IAC port on the Throttle Body and let it sit
6. Spray some Carb/TB Cleaner on the tip of the IAC Solenoid and wipe clean (Do NOT forcefully twist or push the plunger - You will damage the Solenoid. Wipe very gently.)
7. Spray a little bit more Carb/TB Cleaner in the IAC port on the Throttle Body and wipe clean with a thin/lint-free rag
8. Reinstall the IAC Solenoid (Make sure you don't lose the rubber gasket on the solenoid)
9. Reinstall the sensor connector and airhat
10. Reset the computer: Engine Code Index (Check Engine Light?)

12.35 volts is fine if the engine is off, if the engine is on it should be reading closer to 14.4 volts
if that 12.35 is with the engine running replace the alternator and battery

ITS FIXED
I cleaned iac and throdle body and still ran like crape with no idle so as I was told by several members on this site I load tested the battery and it failed. Bought new battery then reset ( rebooted ) computer and now my durango starts and runs better than it has for a long time.
once again this site has showen me why its the best site around. Thanks

Awesome to hear you got the problem isolated and fixed. I once had a battery just like yours (some walmart everstart brand, I just called it a neverstart) that failed under load. Since I'm a poor, my redneck fix was to always have my foot on the gas and brake at the same time, but hey I could do awesome burnout starts at redlights haha.
