My car makes a buzzing sound when accelerating, im trying to pinpoint the cause not cannot not find any information about it. I've checked power steering and it is fine and I've tried to see if it was the a/c compressor by turning off the ac but the noise continues to occur.

Do you
have the same problem?

This could be a heat shield from the converter hitting and when the engine torques it may rattle against it causing this. Unfortunately not being able to actually hear this sound it's better if you take it to a pro who can hear it and do some testing to try to determine where it is coming from.

Was this
