Engine Mechanical problem
1990 Ford F150 V8 Four Wheel Drive Manual
----------------------------------------------------------------
After driving the truck for about 30 mins. the truck will not idle when I come to a stop. If I rev up the motor then it will idle. The mechanic fixed a couple of vacuum lines and the line to the smog pump and said that the problem was fixed.

Have the idle air control motor/valve and throttle position sensor and EGR valve checked and tested.
