ENGINE VIBRATION AT TIMES

2003 Ford Expedition • V8 4WD Automatic • 60,000 miles

* I have a 2005 expedition. At start up, sometimes engine vibrates/hesitates to near stall. I shut engine off and restart, then ok. Doesn't always occur. Have noticed at times a low level engine vibration at idle. Oil is always attended to. Engine light NOT on. Gasoline stations have been varied, using regular.

Clean out the idle air control valve and see what happens
