Only one, my fall back answer, check for vacuum leaks.

They can be crafty, splits in hoses, bad fitting throttle body to
plenum (shrunk gasket there), bracket mount for fuel press reg on
plenum (needs to be sealed with goop), etc etc

  OK, at long last I finally have all 3 of my Vanagons running. I got
the last of the injectors back this past Friday after servicing by Rich
Cruzin at Cruzin Perfomance. Installed them, turn the switches - and all
three engines fired right up. I'm happy as a clam in sand. Rich did a
good job and the injectors now perform well.

What I am not so happy over is that my Dove Blue 88 GL w/manual tranny,
and my 91 Carat do not idle well. The 88 GL idles at 1000 rpm and the
engine hunts up and down from 1000 to 1200/1300 rpm. On the Carat with
automatic tranny, the problem is similar but the hunting is up and down
from 1000 to 1500 rpm. I'm mystified by this. Two separate vehicles -
same problem, almost same rpm range. - one manual tranny, one automatic.

Any suggestions??

Thanks.

John
