Subject:Cold stalling...exhaust smells like fuel
From:Eric Unrau

Hi all,

  I've been have some stalling problems with my 89 Westy lately.  For the first 2-3 minutes of driving when I come to a stop, the engine stalls or nearly stalls.  If I keep my foot slightly on the accelerator at idle I can easily keep it running.  The engine doesn't have to get to normal operating temperature to idle smoothly, I only have to drive a few blocks and then everything is ok.

  Also, I have noticed that the exhast has a raw fuel smell  during the first 2-3 minutes after startup.  This goes away once the engine warms up.

  The 3rd thing that I have noticed is that the engine temperature (according to the gauge) does not get as high as it used to.  For the last 4 years, at normal operating temperature, the temp gauge needle has been just touching the top of the LED.  Lately I have noticed that the needle never goes past the bottom side of the LED.

  Here's a list of everything that hs been replaced in the last 12 months:
  CAT
  Distributer Unit, Cap, Rotor, Wires
  Coil
  Temp2 Sender
  AFM

  I don't know if the 3 symptoms above are related.  If anyone could suggest a diagnoses I'd really appreciate it.

  Thanks
  Eric
