At first starting after sitting for at least 12 to 24 hours have a very rough idle and rough running at higher rpm for about 15 to 20 seconds then it slowly clears and runns fine from then on including all stopping and starting until you let it sit over night again even if you cut off the engine before it warms after initial clearing of the rough start. What the heck is going with this ? O it did start all of a sudden one morning.

First check for vacuum leaks. Also, has the check engine light come on?
