I have no clue what your problem is, but I would take a second to shed some
light on this post. Intake manifolds are all about aerodynamic stuff.
That's all they are is a chamber to direct high speed air into the
combustion chambers. The car would not have to be moving - simply running.
And of course, if that really were the problem, it would be logical that it
would follow speeds and shift points, since both of those affect engine
RPM's.
