Rough Idle/stall at stop.

What is your question?

When the car starts in the morning the car idles normally, after being in drive or reverse when I bring the car to a stop at a light or sign, the car will idle down to 3K-4K and bounce between there and 7K, other times it stalls completely. When at speed I do not notice a loss of power, and at stops I have to keep the accelerator slightly engaged to keep the RPMs up to 8K so it will not get rough or stall. The car has 118K miles. I don't know if maybe it needs plugs, fuel filter, automatic clutch failing...
