There's an adjustment in the cab right next to your fan speed control...it's bout the same size and is labeled, 'Idle Control.'
Okay...I'm lying.
If you have a newer Dakota, you can't adjust it. It sounds like your IAC is dirty (they get covered in carbon) and needs cleaned. What you need to do is remove the throttle body, remove the IAC (back of the throttle body--held on by two torx screws), gently wipe the end of the IAC off without pushing, pulling, or twisting the pintle (or whatever it's called). Spray it with carb cleaner as you wipe it off to help get all the carbon off. Once it's nice and clean, reinstall the IAC and then reinstall the throttle body (use a new gasket...costs like $2 at Advance Auto Parts...they'll prolly have to special order it for you which takes a day or two).

I'm new to this... So, hello everyone!... I didn't catch which year Dakota you had. Some 3.9 and other engines you cannot adjust the idle manually. Idle is controlled by the IAC (or ICM, depending on who you talk to). The IAC is is controlled by the computer. You may want to check for vacuum leaks visually first. If you can't find any use carb cleaner, ether, etc. and spray around the intake area. You may also want to check to see if your timing is adjusted correctly. If the timing marks are moving around and your distributor doesn't use a vacuum advance, check the hall effect under the pick up in the distributor. Unfortunately, the easiest way to get to the hall effect is to take the distributor out. It's not all that hard to do. You do have to make sure it goes in the same way it came out. Post again if none of this works out.

What have you checked so far? Was there some type of repair done previous to this idling problem? Does it do it more when it's cold, warming up, or at operating temp?
I have a 90 3.9. I'm sure Dodge didn't revert back to a manually adjustable idle screw. Although, it's possible the idle can be set-reset with a scanner. Even then, it seems to me the IAC may be sticking. If you rev the engine from under the hood you should see the IAC move fairly fast. If it moves real slow perhaps a new one is in order. Otherwise, check for vacuum leaks. An O2 sensor may not set a trouble code if it's reading within specs (even if the readings are wrong). The O2 should have fairly consitant readings. I'm not sure how much jumping around is considered normal. My experience is if it's jumping 100 millivolts or more there is either an injector problem or the sensor is bad. Sometimes the O2 will read consistant, but be show really low or high readings. Check the specs first before replacing it. OH! Check the PCV to make sure it's not clogged or stuck. Just trying to give you what I've found in my experiences. Hope it works out!!
