Fuel Starvation sounds like the problem then.

The "fifth" injector starts it - but after that
small burst of fuel is burned, there's nothing
left to sustain idle. And the fuel pump is noisy.

    CIS does not have an engine computer unless
it has a O2
sensor.  This computer only controls 2 valves at
idle, to adjust
the fuel air mixture.   IF it is a CIS-E system
it then has a
full blown ECU.    82 my guess is no computer at
all.
   These are very simple....  Check the idle air
valve.
Then check for fuel line clogs.   There is a very
small
filter in the fuel line bolt right on the fuel
distributor.

I have little understanding of Bosch  CISfuel
injection.This is an 82 Jetta CIS in a 82
Vanagon, formerlyDiesel.The symptom: It starts up
runs a few seconds anddies. It will not run
without getting it up in highrpm , which is hard
to do.I am assuming the CIS has an engine
computer butI haven't located it yet in the
vehicle.So does anyone know how CIS works, or any
idea onthe cause of  the symptoms? It ran fine
300 milesand, this has gotten progressively
worse.It has a Pertronix
ignition.ThanksRobert__________________________________________________Do
