hum / buzz when hot
I have a 1998 f 150 5.4 4x4 with 109000 miles.
After a fews miles of driving and the motor is hot, When the motor is restarted there is a buzzing / humming that comes from or near the device behind the fueling intake body. The noise will stop after the motor is run a few min. Any ideas?? The motor runs fine and there is no engine light.

Hello sray1027 and Welcome to FTE! Sounds like the idle air control valve. Those things can make a ton of noise when they act up. You can try cleaning it but with that many miles I would replace it. They can cause your motor to run odd at times to.
