The same thing is happening to my fathers Citroen..It's a CAV. It can happen
at any speed over idle ie in traffic. The car surges forward likeit has a
turbo. However it'san N/A! no oil burn; no smoke out back. Pump is not
loose. I'm thinking it has something to do with the governing springs. Maybe
some slackness there...
