This could be a variety of things related to air and fuel delivery to the engine. There are a few things that are common to go bad and cause these types of problems. If the mass airflow sensor which regulates the flow of air into the engine is not working properly it can cause this to happen. This can also happen when the idle air control module is not working properly. This is also a module that regulates the air flow at idle. I would suggest having an expert, like one from YourMechanic, come to your home to diagnose the misfire and other symptoms firsthand for an accurate repair.
