HIGH IDLE

1991 Ford F-150 • V8 4WD Automatic • 87,000 miles

I have a 1991 ford F-150 v8 5.0L. When I start it up it idle's at about 1300 rpm's and will jump around alot, sometimes the truck just cuts off. I've replaced the EGR vavle and throttle control sensor, but the truck still idle's around 1100, what else could cause the high idling?

Clean out the idle air control valve and see what happens

I replaced the IAC motor and continue to have the high idle issue - did you get this corrected
