i have a 94 dodge Dakota with a v6 magnum motor, i had an idle issue with it. the issue was it started rough and would idle rough and died. or if i sit at a light it will idle down and die. so i changed the spark plugs wires distributor cap and rotor. that some what fixed the issue for a little over a week. Now the the issue is back and worse than before. When i turn the truck on sometimes it idle high then slowly goes down or it barley starts up and idles really rough. i also changed the idle positioning sensor. what do i need to change now? also i dont have the power i should. when i go down the road the idle will jump as well.

vacuum leaks, throttle body, idle air control motor failure, map sensor. any of these could cause the issue but need to be vrified before throwing parts at it.

idle sensor?????

i looked for vacuum leaks already and found none, and yes it was the ips sensor? its on the throttle body, there is three sensors there.

it wasnt the throttle position sensor there was another one, i changed it because the guy at oreilys said it could fix it and it was only $30. Where is the idle air control located?

ok could that account for my idle sometimes being high and other times being low when i start the truck? when i changed my plugs and all that it fixed the problem but it came back.

it is not a sensor. it is a motor. no, it may not throw a code if it is performing its job.

you may have throttle body issues here. i think you need help from a shop. i cannot verify anything here with out me touching it.
