I think that if it was the head gasket, the hesitation would disappear
gradually as the engine warms up and dispose the moisture. My problem
was more intermittent, the car could be ok immediately after start and
then a few returning hiccups before it had cleared. Since MOT was in the
offing, I treated the petrol tank with a course of "D-Tox" made by Comma
I have some confidence in Comma as I have used their antifreeze. The small
print on the box said it was Catalyser friendly. Anyway, I did work very
well. No more morning hesitation or flat spots. Today it passed MOT with
no prob.
