Dear JFAZ,

I have not been able to solve my idling problem. Actually, after reading my orginal post, I exaggerated on the RPM. Actually when in park and neutral the RPM is around 700-800, then in Drive,L1,L2 and Reverse the RPM oscillates between 500-800 the car runs rough but won't stall. The problem is intermittent, so I've learn to live with it. I've read on this forum that the problem could be the
1. Mass Air Flow Sensor
2. Idle control valve
3. Actuator (I don't think our M103 motor has this - anyone please confirm)
4. Vaccum leak

The only thing I've tried to do is to spray carborator cleaner - it helped out somewhat, but the problem is still there. I think I have to remove the whole air filter assembly and clean out the idle control valve.
