I have a 2004 sebring convertible. 6 cylinder engine. Auto trans. Little bud has a problem. Sitting at stop lights, I'll get a really rough idle and it feels like the car is gonna stall out. It will kinda shimmy before "settling" and will continue the cycle until we start moving again. Once it's moving it's perfectly fine. It also tends to rev sometimes at start. Not all the time but sometimes. Opinions? Is currently in need of an oil change(but what car isn't).
What makes this problem better or worse?
hasn't done it since I replaced the Intake sensor until today. Revving started after replacing battery which is under the air intake. For reasons.

Hello, sounds like an engine performance concern related to fuel and air ratios. With too little or too much air per the fuel delivered to the engine, rough running or high idle can result. This can be due to sensor readings, and air leak, or some other fuel delivery concern.
It's all a guess until hands on testing using proper diagnostic equipment is done.
