A few days ago when I started my car up in the morning, the engine did something very troubling! It shook/vibrated back and forth a lot - it felt sort of like it were an MT car and you were trying to go from a stop directly into 3rd gear. It shook me/the car foward and backwards a bit. I'm sure anybody who has mis-shifted know what that feels like - this was similar. (But my box is an automatic)

What would a possible cause be and could this be a big issue? No CEL, humidity that morning was incredibly foggy and cool. After she warmed up, all was swell.
