THe hemi idles smoother; there was a small vibration felt in the steering wheel at idle which is gone; also runs quieter and throttle response is immediate with no delay now. When MDS kicks on, it is much smoother and quieter now.
So, I replaced a number of things one at a time, to see whcih one made a difference and here are the results. There were no codes thrown, which the dealer and most mechanics will tell you you don't need anything and they can do nothing unless you see one, which it BS.

First, replaced the EGR; $40 from Advanced auto; made for an improvement in dirvavbilily, smoother operation, better idle and tip in throttle response.

Second, replaced the PCV valve; $23 Rock Auto; also improved throttle response, and the catch can barely gathers any fluid now; about on eounce in a month (wintertime), where it was collecting much more with the orignal one.

Third, replaced the MAP sensor; $24 Rock Auto, and she really hums now.

I have 72k on the OD, and would highly recommend replacing all these at the 60k mark for the Hemi; total cost for parts was under $100.
DMS, any chance you have those part numbers handy? I'd love to pick up a new PCV valve and the new MAP sensor for my 05WK. I've noticed recently that my catch can has been picking up A LOT of goo, but hadn't got around to replacing the valve. I can't see these pics at work, but I'm sure they'll really help with the MAP sensor replacement. My mpg is always poor with city driving, but anything to make the motor run a bit smoother is worth it!

FYI, my catch can fills up quickly in the winter as well. I empty it every couple of weeks, where in warmer temps it collects very little.

Since you haven't responded yet, I'm attaching some screenshots. Which model from the attached screenshots did you purchase for each? Thanks in advance.

Also, surely it isn't normal for my catch can to fill to FULL within 2k miles in the winter?

Yes, my catch can can fill up in 800km of really horrid weather. Just get into the habit of emptying it every fuel stop

You should look into the conditions i drive and have a through understanding of the jeeps service history before making sweeping statements.

My jeep is a 5.7, not a 3.7 Sunshine, completely different animal. lf i want advice i will ask for it, and usually listen to that of direct experience rather than 3 hand regurgitated material from someone with so much time on there hands as to find it necessary to dole out unsolicited advice.

First off, I was only trying to help so stop being ungrateful. Secondly I know you don't drive a 3.7 and I know the conditions. Thirdly, I am a mechanic, so I have all the time to know what I am talking about to "dole out unsolicited advice". And for your information the 3.7 and 5.7 pcv valve are actually pretty similar. If you did not want advice then dont post your problems on the Internet.

Ps. Dont call m3 sunshine. Im not some punk kid who don't know anything

Regardless of how you're reacting, he's probably right. A catch can filling up THAT quickly generally would indicate a bad (stuck open) PCV valve.

A catch can shouldn't be full in 497 miles, regardless the conditions and driving habits. That was why I suggested a pcv valve

I have a new PCV valve, installed the hole facing the rear too, and the CC fills up in less than 1000 miles during these cold months. It has always done that in winter, with the old PCV as well. No biggee to empty it out. ITs not the valve, since it collects very little in warm weather.
