i would try disconnecting the negative battery cable for 10 min leave the postive hooked up, this wll erase any stored memory in the prom, im mostly a Ford ECM tuner guy but im sure Chrysler has somthing similar, even if you dont have a code or engine light it still can effect drivabilty, this sorta Keep alive memory could be storing troublesome info and could give these problems specially since you changed you TPS recently, keep us posted, i might have a few more tricks!!!

How many plugs does you 4.7 have? Im not sure which year but Dodge started putting 8 plugs on the 4.7 too sometime between 05 and present. Probably with the introduction of the flex fuel engine. How does your air filter look? You have done replaced almost any sensor that would cause this. Start researching transmission filters on these trucks. When I bought my truck and was beginning to do the maintenance dance that I do with any used vehicle I buy (fluids, filters, battery, etc) I found that the transmission has 2 filters in it and began searching for info about it. There is a flat filter for the transmission itself and a spin on for the cooler btw. During my searching I read of a defect in some of the spin ons that would make the truck act this way and sometimes stop at random. Might be far fetched but worth a shot when the people who are supposed to know the most about these trucks are scratching their head. Also check all of your fuses.

I hope you get this worked out. I know from experience that there is nothing more irritating then a small niggling problem that cant be traced down on a truck that you just bought. I have also noticed that when I do find the problem in these situations it always seems to be 1 small stupid little thing creating all the havoc.

what does your spark plugs look like?, also see if you can have your Plug coils checked for malfunction, but the plugs should tell you right away where your problem is, also check the gap!!!

Use can use a volt meter to test a TPS, however, unless there is a hugh open in the TPS, you will never see it with a volt meter in ohms or voltage readings.

The only way to see a small open is to use a graphing volt meter with a high capture rate. If there is an open you might see a one pixel line (or more) drop off then come back. If you have the availabilty of a high end Fluke meter, use that or just get another TPS.

Just bought my 05 4.7 Ram, Same missing at idle. I believe it was a stuck valve due to carbon build up.

Here is a quick test for you to do. With the truck at idle start disconnecting the coil packs one at a time, if the engine starts to miss worse then you know the cylinder is firing, plug it back in & move on to the next until you find the dead cylinder. If one of them isn't firing then this will find it.

Once you find the dead cylinder then switch coil packs with the next cylinder over & restart the truck & pull the connector off of the dead cylinder, does it still not change or is the other cylinder now dead? If it's still the same then pull the injector plug off and see what happens, at this point you can swap injectors around like I did, and then swap the spark plugs. If still no difference then I'm betting your valve is stuck on that cylinder.

In my case I think I got lucky, I ran 1/2 bottle of Seafoam through the brake booster vacuum line & let it sit for 5 minutes, then restarted it & ran the crap out of it for 30 minutes. The miss finally just stopped and now runs smooth as can be. Just for added piece of mind I also added 1/3 of a bottle of Marvel Mystery oil to the oil, ran it for a couple of days and did an oil change. I added 12 ounces of Marvel back to the fresh oil as well (helps me to sleep better at night) To my surprize the old oil that came out was clean without any crap in it (I strained it!)

This is what happened in my case, yours could be different, TPS, ECM, rocker arm falling off, etc, etc. I'm new here & the Vets can help you if it turns out to be something else.

I think it's a good place to start & it's all free as you're just swapping parts around & not buying any. shouldn't take but 45 minutes to do all of this with a ratchet, extension, spark plug socket, flat head, and a few small metric sockets (8 and 10 I believe) If you do end up pulling the injectors to swap them, bleed the pressure out first and just know that there will still be plenty of pressure left so have a towel handy. Oil the o-rings back up before you re-install the injectors.

Please post your findings.
