Faint Whining/Wheezing sound when accelerating.
Recently, I noticed a faint whining and wheezing sound when I accelerate my 1999 Civic LX (it has 171000 miles.) It sounds almost like the sound that hybrid cars make except fainter.
Does this sound like something very serious that I need to get checked out at a mechanic ASAP? Or is it something that could wait till my next oil change next month?
