This alters the fuel/air mix in an uncontrolled manner.

With the engine fully warmed up, running at a predetermined RPM, this valve clatters like a fuel injector as long as a vapor recovery test is not being performed.

Next time this happens try holding the gas pedal down to see if it helps.
Thanks. I'll check it out if we still have a problem.
