Could be a idle air problem. The injector could be leaking when you shut it off ..Try some injector cleaner see if it gets better..The idle air shouldnt run rough just idle real low or sometimes it will get stuck and idle high....Are you losing any antifreeze..If you are the 2.0 SOHC engine bad about leaking antifreeze into the cylinder and makes the engine run rough until it burns it out..See if you can see the smoke coming out when it happens..White smoke indicates antifreeze,,Black smoke indicates fuel..
You will have to get the trouble codes read from your car, to know exactly what is causing the check engine light to illuminate and the rough idle. Most major auto parts stores will read the codes and give you a report printed out, for free.
I had a something similar to this happen to a girlfriend of mine. She has a 98 escort and it ran out of gas and the service engine soon light came on after she filled it up. If this is what your talking about check your owners manual. Most of the time if there is really nothing wrong with car you can drive it around ( Generally 20 min in town and 10 on the hwy with 4 idle periods (4 times of the engine being at idle) - do not cut engine off) and the light will go off. The rough idle code most likely happened when the engine ran roughly because. it was running out of gas.
I would take it to a local Auto Zone, or Advance Auto, they can run it through the diagnostic computer and see what codes are tripping, most likely it's going to be for a cylinder mis-fire, i would try making sure all the plugs are good, and check and see if all the plug wires are secured tightly.
I would check for any vaccum leaks,
You can take a spray bottle of water and spray around the intake manifold with the car running at idle.
The idle will change and get worst if the intake is leaking.
The intake gaskets could be the failure. I know autozone can get into the computer and clear the codes for free.
