Hi all,
been having an issue with my Previa, in that the engine has a whistling at the intake manifold when it idles and is direct proportion to the throttle position, so when I hit the gas pedal it goes away and returns as soon as I let off on the gas. Not engine rpm but gas pedal position affects this noise. Any ideas on what it could be?
Thanks...
