May sound stupid, but I never noticed it before. With the key in the ignition position but the engine not running, I notice a whining sound coming from the throttle body.
Is this normal? Probably it just priming itself for start. I know alot of cars do make noises similar to this. One example is a Hyundai which make a loud ticking sound with the key on engine off.
Am I just now noticing something that's always been there? Does your car do this?
I have an 06 wrx.
