I have a 2007 Dodge Charger 2.7 V6. It recently developed an extremely rough idle. When the engine is cold, the engine seems to run and idle fine. Once the car is warm the whole car shakes at idle. I have replaced the spark plugs thinking that it was a problem.
Changed spark plugs. Cleaned air filter. Seems to have had a slight misfire when idling before this issue. Now entire car shakes when the engine is warm.
