Just new here and I just read that there have been revised, "hotter" plugs for the Sebrings... I would be interested to know if they are Mopar or not? I changed the plugs in mine a couple of months ago with Champions, and it has been idling rough lately. I have been thinking 02 sensor, etc. but this is worth a shot too.

 

champion yes if u don't have an check engine light on for an 02 issue don't need to change them it wont fix anything.

 

Rough idle is caused by many sources, but a common one is a leaky EGR valve. They also don't throw codes frequently.
