Sorry if there has been a reply to this ... my email is all over the place.
If carburettor then if Zenith type you could have a split diaphragm.
I don't think in the 9000s came with carbs though, just injection
(right/wrong).
Without getting into complicated eletronics (I cannot work out in my head how
injection cars would work) it sounds exactly like fuel starvation and/or
incorrect timing. Here is a couple of pointers for cars with
electrical+mechanical systems (if injection + engine management the cause can
be the same but you have to know which sensor does what).
Two things happen on accelaration. 1. Your distributor advances because of
the extra depression in the manifold. 2. Extra fuel is supplied to the
engine. THUS, early spark + more fuel = accelaration
Yoy have either one or both of the points I mention above. Once the engine
is running at a constant speed (under load or not) it is fine, because the
equilibrium has been set. The Distributor stays at its normal position and
the fuel supply stays constant too.
Hope it helps a bit
Charles
