My 2005 Town & Country has given me quite a few problems lately. Recently the van runs at a rough idle at a stop light and takes off hesitantly. The check engine light comes on for a few days then turns off for a few days then comes on again. All the while it continues to have that rough idle. During the rough idle, the rpms don't budge, which seems a little strange.

 

whats the code for the check engine light?
