2000 Dodge Intrepid wont idle

i have a 200 intrepid that wont idle while in gear and not very good in park. I have checked the codes and they were the map sensor, the front O2 sensors and one that said it was running rich, i replaced the map sensor, O2 sensors and the coolant temp sensor and they didnt change anything.When and if it idles in park it smells like raw gas and kind of spudders. If you keep your foot on the gas and brake ur alright. I dunno where to go with it, it goes through gas like crazy.
