was it just a blurp or continuously, making it difficult to drive?

my thoughts;
if you have an aneroid (castle like thing on top) diaghram on the IP, leaky
lines connecting to it my cause symptoms like that I suppose.
Since the throttle shaft does not command the pump directly but does so
through a govenor and spring, I suppose something internal maybe...
unlikely.
Air in the pump or lines, if it's been setting for a long time.

 btw, my 04' jetta (BEW engine), did that the other day startup, freaked me
out, but hasn't done it since.
