I replaced mine and I still get rough idle and the air suckin noise so I'm gonna go with yakkier's advice and have a vacuum test done.

Please, do not start new threads for the same problem. Threads merged.

Here if you decide to replace your IAC these pics might help a little bit, i replaced mine a week or so ago.

So... Silly question.... I removed my airbox with my carb cleaner in hand, I removed the TPS and replaced it.... now there is a sensor looking directly at me pointing straight toward the front of the truck... I removed the two bolts holding it in place and it didnt want to come off, so I didnt tug... Is this the IAC, if so how do I remove it> Thanks again guys... If anyone lives close to Nebraska, or Council Bluffs Iowa when my truck is fixed we are all getting tanked on me at the casinos!!!! Thanks again!

The sensor pointing towards the front of the truck is the MAP (Manifold Absolute Pressure) sensor. You have to tug on it a little to get it off. Remember to put the little rubber elbow on the bottom back on the throttle body when you put it back on.

The IAC is on the back of the throttle body. Yakkier had a great thread on how to clean it.

Got it thanks... Im going to have a busy weekend.... but just want this problem licked... Thanks again guys!

Where is the Crank Position Sensor located on the 3.9 v-6 Ram, Is it easy to replace? Thanks

On almost all vehicles the CKS is located somewhere on the transmission bellhousing or near the joint between the tranny and engine. Please fill out your profile info, it makes it easier for us to identify what truck you have.

It is mounted to the back of the passenger side engine block. It is a PITA to get to.

OK GUYS, Replaced my IAC, and my TPS.... STILL BOGGING DOWN AT RANDOM STOPLIGHTS, Runs like a dream... when I stop it will bog down if I put it in Nuteral give it gas it picks right back up.... No check engine lights, and when its boging down I hear a Hissing from the throttle body? Any suggestions? IM Tired of replacing random sensors and parts... Im at about 2000 bucks now..
