I have a 2008 Toyota Matrix with 56k miles on it. Recently it starting to make a whining sound when accelerating. It’s very subtle, but kinda sounds like a plane taking off. It seems to go away once the car is moving/maintaining speed.
I just got an oil change and the air filter replaced. Also, it seems to idle rougher than it used too, or I could just be paranoid.
Any help would be great.
