Re: [doc] Buzzing from engine

["Stian Birkeland <delorean@xxxx>" <delorean@xxxx>]

Idle speed motor, you say. What is it for and is it dangerous if it 
buzzes? 

I also have to tell that when I started the car, the car idled fine 
around 775 rpm...so if its the idle speed motor that buzzes, WHY does 
it do this?

due to the fact it was seized and the motor was straining to turn. 
Not too loud though and you would not be able to hear it over the 
noise of an engine at idle.
