I hear a high pitched whine or squeal when pressing the throttle. Even the very slightest pressure will create this noise. With the throttle held constant I also hear the noise as the car shifts gears. The noise is a very short duration. I do not think it is a belt or bearing noise. Any ideas? Thanks.

  1. Sounds like a vaccum leak…. is the idle higher than normal?

  2. The idle seems normal and the vehicle runs great. I’m hoping to get under the hood this weekend for a better listen.
