Check it with the reader...a pending code won't trigger a light, but it'll be in the system as a fault code. Could give you a direction.
If you have no codes...I'd start with the basics such as checking that you have no vac leaks, etc. if all of the other stuff (like plugs) is good. If there is a leak, the MAF/TB might be trying to compensate, and hence rough idle at least initially.
