I have code P0404 coming up now (P0404 Exhaust Gas Recirculation (EGR) Open Position Performance). Can I clean the EGR or is it a part that has to be replaced? I just had issues with plugs, would that have something to do with the egr error?

50/50 chance cleaning the valve will help. Use electrical contact or brake cleaner. Niether leaves a film to collect dirt. You may have cracked or knocked a vacuum line loose when changing the plugs. Have a look see.

When my car had that code, I cleaned all the connectors first, then I took the EGR valve off and cleaned it. I still had the code. I finally replaced it and everything was fine. My "04 has an electronic EGR valve. I think think they fail pretty commonly on these cars.
doesn"t that code mean that his page is not found?sorry... had to be said. When I had an EGR issue, it turns out that one of the vacuum lines ports on the valve was clogged. never hurts to pull it out and look. You shouldbe able to test the valve as well (check a FSM for how) and see if the diaphragm is working as needed.

Have the same problem on my 2005 Town & Country. Mine has an electrically operated valve. I just posted my results after trying to clean my valve. No success.

Just did the same things as you. The valve only operates after the engine temp gets above approx 50 degrees Celsius, the van is in gear and moving. To test that the valve is pulsing off and on, remove the narrow pipe from the EGR valve that leads to the inlet manifold and then SECURELY plug up the hole left in the inlet. Don"t use a small rag...IT WILL GET SUCKED IN! Let the engine idle until warmed up and take a short drive...if the valve is working you will hear it chattering quite loudly.Mine operated ok and when I dismantled the valve I found that the pindle position sensor was defective...it had an intermittent open circuit which was triggering the EGR code. You can try to open the valve but it"s easy to pull the wires right off the solenoid by mistake. Even then you still can"t access the sensor (which is just a variable resistor). I had to buy a new EGR valve and found that (at least in Canada) an OEM type from the Chrysler dealer was cheaper than any of the auto parts places.
