The past couple days, my car shakes when idling. Once I get moving, then it goes away. Took it to get a diagnostic/oil change at a big shop. They say that my cams are off by 2 teeth from each other. Not sure what this means, since I haven't really looked at it yet. I got my timing belt, water pump, etc replaced a year ago.
The difficulty starting might have been because I had my A/C on. I turned it off and feathered the gas on the next step when it was struggling. Seemed to work.
