I posted this before, but couldnt find the thread to resurrect it.

My Jeep has a 97 4.0 in it.

When coming to a stop while driving it will occasionally idle really rough (gets down to around 200 RPM) but has never stalled, and goes right back to a normal idle as soon as i get to a complete stop. If I hit the accelerator it revs up without a problem.

Before it was suggested that it was an airflow sensor, but after checking at a couple different parts stores they all told me that my jeep doesnt have any kind of idle air sensor or mass airflow sensor

Help pls

might be your torque converter staying locked too long.

You may want to check your idle air control motor. It is on the side of the Throttle body. It is a stepper motor that adjusts to control the idle speed.

Yea, clean out the IAC motor and passages with carb cleaner.
