Idle Air Control Motor malfunctioning.
idle air control valve?
Check your TPS TPS = throttle position system
on the left side of the intake is a round cylinder with wires plugged into it. this is the idle control. It is most likely dirty. take it off and clean it out with carb and choke cleaner.
i have a 1988 Ford Bronco XLT 5.0 4x4. The truck will start and idle for about 15 to 30 seconds then acts like it has no fuel and dies.
by the set screw on throttle cable
timing is advanced to far
It was my TPS sensor. base voltage was reading .5V too high.
start up your bronco,let it idle, pull the tranni dip stick and see if there is nay oil in the tranni
How high is your idle? idle should be 800rpm good oil pressure is obtained at this idle

Check the TFI module. It is located on the distributor.
