[200q20v] Prices(stalling)

[Gary Martin]

Probably needs a turbo bypass valve. The best way to check it, IMO, is
follow the hose from the TBV that goes to the back of the intake manifold.
Disconnect it at this point, and draw a vacuum of about 6 pounds. I used a
vacuum pump purchased from Pep Boys. It should hold this vacuum. If it
doesn't, it is either a bad hose or the TBV. Take out the TBV and apply
vacuum to this same connection on the TBV. Doesn't hold? need new TBV, if it
does, hose is leaking.  See site http://www.sjmautotechnik.com/ for more
info on TBV.
