[DML] Re: Engine Dies at idle HELP!

["dmcchaser" <dmcchaser@xxxxxxxx>]

  I can't remember if you ended up getting a fuel pressure gauge while
you were hunting for the cause of your failed emmissions.  If you've
got one, hook it up and watch your fuel pressure.  If you don't have
one yet, I strongly suggest getting on as it will take out a lot of
guesswork.
  All your noises sound normal, the "hunting idle" seems to be a
hallmark of our cars.  I will conquer it one day though *sticks flag
in sand!!*  Ahem...
  Get someone to help you, remove the air cleaner assy. and have them
start the car up while you stand by the engine (all the usual warnings
apply here, don't get run over, don't wear ties or loose clothes,
don't touch hot things, don't lick the drive belt, etc.) Twist the
throttle pulley slightly and press down very  slightly on the metering
plate (that 6" or so disk on top center under the air cleaner housing)
this will admit more fuel, careful a little bit goes a long way.  If
the engine runs better, you might be too lean, though we don't know
the cause yet.  If it runs worse, it's too rich.  Again, we don't know
the cause.  Be careful when pressing down the plate, you just barely
need to move it.  If you push too much, and admit too much fuel the
engine will run poorly anyway.
