What in the world IS THIS??
#12
I'm having a rough idle when it is cold. Even after the engine is warm and I'm at a red light or stop sign, the idle seems low to me, and will occasionally have a short stutter or a "miss" (if "miss" is the right way to describe it).

Ok, I just read your original post and see where it's running like sh&t.
Well if that hole is supposed to be capped you'd be losing vacuum big time and that would at the very minimum produce a CEL. Athough I guess I'd block it off temporarily to see if it made a difference
A "miss" is short for a misfiring cylinder, also would generate a CEL.
My first guess would be TPS. But two things I'd try first would be to reset the PCM (sometimes this fixes a low idle situation) and I'd ground the throttle body (something the engineers never found necessary but makes a HUGE difference in throttle response). They are free fixes and won't hurt anything.

It does seem to have a nice smooth acceleration now, but the rough idle and general crappyness is still there.

Cold Air Intake. I used to make them on the cheap as kinda a side hobby . Have even made and installed about a dozen or so for DF members but haven't in about 5 years or so. I probably haven't put one on an '03 since probably 2008 that's why I'm not remembering if that hole should be plugged or not. But I did remember the PCV was on top and there wasn't a line or hose coming off it.
Ground that new TB. If you want to see the difference it makes, take your meter and ground it, with the engine running touch positive to the housing and read the Ohms (interference). The ohms build and the plate reacts slower and slower to the fly by wire signal coming from the gas pedal. If your touch a wire to the TB housing and to chassis ground you'll watch the meter drop to zero...

If that hole is supposed to be there, what do you think its purpose might be?

No clue, like I said the '03 was the first year of the Hemi Ram and it's a red headed step child.
Here is a CAI I made for an old member with an '04 and if you look at the circle you'll see I rerouted the PCV to collect in that small filter instead of leaving gunk in the engine. You'll note the metal tube that P23851 was referring to that the '03 doesn't have.
