[DML] Re: Idle Speed thermistor

["deloreanfl" <ericp@xxxx>]

John brings up a great point,...
When measuring high resistance values, or voltages with very low 
current (such as the Lambda sensor) it's always a good idea to use a 
decent DMM (Digital Multi Meter) or DVM. The internal impedance of a 
DMM is very high, and won't load down the circuit you're reading. 
Some analog meters have a low impedance and may give you an 
inaccurate reading by changing the circuit you are reading.
