Is there a microswitch that is activated by the accelerator linkage— this switch ordinarily (84-89 911 models) closes when 'off the accelerator', and if you are above some DME set engine speed (e.g. ~1200 rpm) the DME will modulate the injectors accordingly. If you’re below this 'measured' RPM, (i.e., switch is closed @idling) it will override and not shut-down the injectors...

In short, if the 'measured' RPM is incorrect that might give rise to what you described above...
