it sounds like it is coming from the intake but im not to sure and the sound is very frequent especially when im driving or in idle
i hit the gas on car and it makes a short hum sound by air filter what cud it b on 2001 Mercury Cougar
Ford has had a problem with the IAC motor going bad causing a humming noise like a kazoo.
would the iac motor cause my car to stall out coming to a complete stop or when i put car in park? and would it be better to just get a new car with the iac problem or is it a fix for a decent price
