Having problems with your 1999 Ford Explorer ?
Rough idle no check engine light on starting to stall when making turns at low speed like in the drive thru radio lights flicker
Did not specify rpm, but sounds likely to be a idle control valve, it adjust engine rpm when a demand or load is apply like turning your wheel, so the engine dont die. try cleaning it, if not enougth carbon build up found in it, replace valve.
