Hi All,
Power steering pump just went on my 2004 gt and while i was looking around the engine bay prior to removing it i had the ignition on reds but the engine off and i noticed that there was a steady electric buzzing coming from the throttle body. This being my first drive by wire car I just want to ask if this is normal for our cars or if the throttle body is stuffed. I have had intermittent rough idle which i tried to do the avcs solenoid clean up to fix but haven't had a chance to thoroughly test it. Is it possible that the throttle body can cause rough idle if it is faulty?
Cheers Kab
