Q: Car is making unusual sounds - 2004 Chevrolet Impala

asked by on October 22, 2016

The car is making sounds like a lawn motor. Appears to be coming from the passenger side of the hood. It is only heard when the engine is idle. When the car is in park it is the loudest, then changes when in reverse, & again when in drive.

My car has 195000 miles.
My car has an automatic transmission.
