Most of the time your engine will spit out the check engine light which you can go to most auto stores and get the code reading service for free, this will allow you to know what your engine is saying is not right.
With my old ford escort when my spark plugs got too lean, I lost some SERIOUS gas mileage and engine performance. My idling wasn't that rough though but I did have some issues with it.
Your converter could be clogged up which would make it idle ruff.
Is it making any odd noises?
