Question about Dodge Dakota
You don't Say year of the truck but here is the most common cause, it is a sludged up automatic idle speed control system, the procedure below fixes this problem most of the time, this assumes u don't have a check engine light coming on or any computer comntrol fault code in memory.
Follow the instructions exactly please.
I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

If you have no check engine codes I would look for a vacuum leak first.
You can check vacuum hoses by spraying a light coating of WD-40 on them and seeing if the roughness stops momentarily. Or you can use a vacuum guage. Either way.
If you do have an engine code see if its related to the MAP or IAC sensors and we will go from there.
