i don't know that vehicle very well... but there are usually bolts/screws that hold them in place. 4 to 6 of them per cover. sometimes the spark plug holes have giant nuts that hold the cover in place.

one, five, three, six, two, four
The plastic intake should have this sequence molded into it somewhere, and even the corresponding cylinder numbers in front of their respective holes. Have fun, and thanks for posting on Fixya.com

SOURCE: replace valve cover gasket
I have the same problem on a 2003 Town & Country. The cover for the front 3 cylinders is quite straight forward, but in order to do the rear cylinders I believe you are going to have to remove the cowling below the windshield. You will need a gear puller to remover the windshield wipers first, then remove the cowling. Than should give you more room to work. It's still not going to be easy, but it sure beats paying hundreds of $$$$ in labor charges.

If I remember correctly if you look at the back side of the fuse cover, it should tell you what the fuses are. Also in the owners manual in the index, under fuses, it should give you a diagram of the fuse location for the acc. outlets. Good luck. The fuse should be a 20 or 25A fuse.

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.
It could be other things also but this is where I would start.
