2002 Ford Ranger runs rough at idle but no OBS code?

2002 Ford Ranger runs rough at idle but no OBS code? My 2002 Ranger runs rough at idle. If I goose it a little, it goes into high-idle for a few seconds, but starts to run rough like it is lurching back and forth.

Clean the Mass Airflow Sensor. Have the intake manifold checked for leaks (smoke test)
