There is a small vacuum line from the fuel pressure regulator to the manifold body. Look for a leak or cracked line, or a defective regulator.    Jack

  My 86 westy is running very rich with spark plugs becoming sooty after a
  dozen miles or so resulting in a rough running engine and some black
  smoke at the the exhaust. Compression is good , timing and idle at
  specs.  tempsensor2 checks out although it is difficult to get a
  reading. Replaced the idle stabilizer valve(it needed it}.  What are
  some of the more logical  things to take a look at?  How does one check
  out the oxygen sensor?  Any suggestions would be much appreciated.
  Thaking your in advance,
  Alex
