I am driving my son's 1997 Hyundai Tiburon. When I first start it up in the morning it runs very rough. If I turn on the air conditioning it runs even rougher. I try to drive down the street and it runs horribly and just lopes along. Once it has warmed up a bit it runs fantasiclly.

Any check engine light? does it overheat? use coolant? If th eengien light is or has come on,. have it scanned for codes, it will probably have a misfire code that will point to which cylinder to start with. Could be an injector bleeding down overnight, or spark issue or a very slight head gasket leak that is wetting the plug with coolant
