Ok, a rough idle could be caused by many things... lets go over the basics.
When last were the spark plugs and the plug wires changed?
Are you using quality gas, and 92? Try a bottle of TECHRON in the fuel system.
When last was the fuel filter changed? This caused a rough idle for me.
What about your air filter?
These are the common, more likely reasons for a rough idle.
But if you would tell your model car, year and mileage, it'll help us out further to assess what else could be your problem. GOod luck.
