I think I know what it is...I believe the plenum gasket in the intake is bad, as I can hear a vacuum leak pretty loud when it does it...and, its coming from that area.

Also...mine will load up so bad sometimes at red lights that I have to floor it to make it move, and it'll just kinda chug along, then, all of a sudden, nearly flip you back in the bed when it clears up...lol

Also...Alex, no it doesn't click...doesn't idle rough and go back idling smooth....just idles rough.

And, the PO moved my IAC to the intake pipe (going to the fender)...so...could that have something to do with it?

Also...as weird as it may sound...seems like it does it more with the air on...strange yes.

hey strange does yours do it all the time or just once in a while

just once in a while, for no reason at all. (no one thing starts it)

hey...just saw your post...

well...I pretty much have it narrowed down to the o2 sensor.

I unplugged one of the o2 sensors and the truck has been running fine for about 3000 miles now...lol
So, I asked a Dodge dealer, they claim that when a sensor is unplugged and the CEL comes on, the computer goes into limp mode...but, I don't believe that one bit.

So...to test this theory, I plugged that o2 sensor back in while the truck was running, almost immediatley it started loading up again.

I then unplugged the other o2 sensor...didn't make a difference. I even drove the truck around the block, everytime I came to a stop it'd load up again.

Got underneath, plugged that one back in and unplugged the o2 I originally had unplugged, and all was well again.

So...now I just need to get under there with a torch and get the old one out. I have a new one I got out of the junkyard (someone had just put a new on in a JY truck and it came right out...haha). But, once I do that, I'll update. Its just getting the drive to do it...haha.
