Yes. The fluttering is due to a failed Bypass Valve. The diaphragm is
probably torn and the BPV is not opening between shifts. The factory BPVs are
$25. There are aftermarket ones from Forge or Stratmosphere, but they are in
the $120 -$140 range, as I recall. Some people have had bad luck with the
factory ones, but mine has lasted 3 years so far. And given the cost disparity
I can't justify the aftermarket ones based on my experiences.
