95 Aspire...Rouch Idling

My Ford Aspire is starting to get a little rough when idling (stop signs and red lights). Seems to "miss a beat" every 6-15 seconds (sometimes as much as 3-5
seconds).
Not sure if it's the cold weather or if the idle speed needs adjusting. What are some basic reasons for rough idling???

Could be any number of things. When was the timing belt changed?
Also, check the fuel pump - it may be putting out a lot less pressure than it should.
