[Vwdiesel] IP on NA Slow Deceleration Response

[H . Hagar.]

Chuck Carnohan  and  ALL . :

To me Hagar that is a perfectly happy normally functioning  Pump  (IP)
IMHO.

All  mine do the same thing if idle is set a tad high.   So before you do anything else
turn the idle down to the " Shaky Jake "  point and then in very very small moves  to shaking stops..
(Hillbilly Tuning)
Remember there is only one  fueling control COLLAR.   . It must move to open bleedholes
instantly.     Internal Governor action is the problem.

>From 0 to 850  RPM   the governor  " RULES "   from about 850 to  5400   RPM
your  foot  " RULES ".        from 5400  to XXXX  the governor   " RULES "  .

The way this was done by BOSCH in this type Pump ?   ----by  " BIAS "   springs.

Remember the Governor is a Min - Max  RPM     -- NOT a variable speed governor.
If your engine braking is non existent   --most likely the Idle RPM is set a tad HIGH.


Hagar.

PS :    All mine does exactly that.   ----  1.5 L NA and 1.6 L   NA   and Turbo   with
the LDA.  ----------   It is a design characteristic  ----i.e.  normal response.
