I get a vibration when stopped at a light with ac off. It seems to happen when its coll out but maybe its just because the compressor is off?

My guess is that engine does not like to idle that low. I took it to the dealer and it was fine for a few days and then came back.

What do you want for $50,000 and engine that vibrates and and transmission that does not know when to do shift. I hear that a new/reprogram for the trans is now available but not sure about a fix for the engine other than turning on the a/c.
