In general, rough idle for almost any car can be caused by plug wires, sparkplugs, injector(s) (depending on whether it's throttle body or port injected), EGR valve, burned exhaust valve or anything that the computer says is wrong. In general, if the engine is giving you any problems and you don't have any specific concerns, run a computer diagnostic test first. But if the engine has overheated, the first step should be a compression test. Good luck.
