Hi,

I just discovered this about my car. When the ignition is on (but engine not runninig) and I move the throttle just so slightly a buzzing sound is heard. If I move the throttle further the sound fades out. The sound seems to come from somewhere below the UIM.

Is this normal? What's making the sound? Should I worry?

 

Some should know if this is normal!?!
Or if not, could someone be kind an check, it takes less than a minute.
