I have been trying to figure out what the deal is with my wifes sebring. Basically the idle is terrible! I have been through all of the vacumn including the egr valve thinking that it was the issue. This only happens when the car is idling. No check engine light. Changed the sparkplug wires, and checked the spark plugs everything was great. Cleaned the idle air control valve, and throttle body. Not sure what else could be causing this problem. I know it's a common issue with the 2.0 litre. Any help would be most appreciated.This problem has been a pain, and continues to be one [:@].

 

ever though about motor mounts?? if it is infact a miss u would get a check engine light.

 

If you didn't REPLACE the EGR valve, but only inspected it, then it is the most likely culprit. They leak inert air into the intake at idle and make a real mess of it. And mostly you don't find any vacuum leaks when you test them. They also don't throw codes often.
