Yes I have, it was the first item I did when I purchased the Z 3 years ago....
It was normal before the plenum pull....that's why I think it maybe a hose that has come loose as the pump runs a little longer as stated above.
Throttle is perfect, closes @0% and opens to 100% @ WOT, as per the Tech 1.
