RE: [DML] Help me please

["Jeff Friday" <DeLorean_Type304@xxxxxxx>]

That's the Frequency Valve which makes the buzzing.  When it's running 
correctly it will buzz all the time and sound like an angry cricket.  Check 
and make sure you plugged in your LAMBDA Thermal Switch (under the intake 
manifold) and that you're Full Throttle Microswitch is plugged in correctly 
and also that the switch is not stuck.

To check your LAMBDA Thermal Switch reach under the back of the intake when 
the motor is cold.  It's the first switch on the passenger side of the 
engine.

Also, what kind of coil did you use?  I have had problems with every kind of 
coil except the original one.  Try putting that back on.  Why replace if the 
car ran fine?

Also, be sure to double check your spark plug wires.  If you did it one at a 
time you're probably fine but I have had these things not want to "click" 
onto the end of the spark plug and it wasn't sparking properly.
