1999 Ford Escort Q&A
1999 Ford Escort Question: loud humming when i'm driving, when i remove my foot from the gas it stops.
Would need more details, but sounds like a bad wheel bearing or a bearing going in the transmission. I would recommend you have it professionally diagnosed. - Chevy Power
Is the 'humming' directly related to whether or not you are stepping on the gas? Is the A/C on or off at the time the noise is occurring? What speed does the noise start/stop at? does putting it in a lower gear have any effect? Answers will help in ruling out certain possibilities. - ziptie12
