Is the a/c on? Rough idle is usually/ cause by o2 censors improperly working causing the map censor to regulate the fuel air mix to your engine. Have you Checked the air filter?

If your check engine light is on you need to have it scanned to locate the problem. Could be a vacuum leak or a malfunctioning sensor.
