My Ford Escape has developed an annoying problem over the last month. The engine compartment produces a buzzing sound like crickets when the gas pedal is pressed down. It stops when acceleration is let up.
Do you
have the same problem?

Try cleaning out the idle air control valve and see what happens

Disconnect the air intake ductwork from the throttle body.

Start the engine, then increase and hold the idle speed to 1,000 to 1,500 rpm.

Spray the throttle cleaner or engine cleaner into the throat of the throttle body, aiming for the idle air bypass port (usually located on the side or top of the throttle body opening). Give this area a good dose of cleaner (about 10 second's worth).

Turn the engine off to allow the cleaner to soak into the IAC passageway.

Wait about three minutes.

Restart the engine, rev and hold at 1,000 to 1,500 rpm, and repeat the cleaning process again.

Turn the engine off again, and reattach the air intake ductwork to the throttle body.

Start the engine and rev and hold to 1,500 to 2,000 rpm until no white smoke is coming out of the exhaust pipe.

If this fails to make any difference, you can remove the IAC valve from the throttle body and spray cleaner directly on the tip of the valve and/or into the ports in the throttle body. Let the cleaner soak awhile, repeat as needed, then reinstall the IAC valve, start the engine and run it at 1,500 to 2,000 rpm as before until no white smoke is seen in the exahust.

Does it sound like two pieces of thin metal being tapped against each other at a fairly fast pace? If so check where your exhaust meets the catalytic converter, there is a piece of sheet metal protecting the exhaust pipe and the welds tend to come undone. I used exhaust tape and have never heard that annoying sound again.
