[200q20v] undiagnosed engine malfunction

[Tresturbos at aol.com]

I bet it's the BPV.  Mine would stall every once in a while as I came to the 
top of a steep hill and decellerated, but not when I did that test.  Now it 
never stalls.  My vacuum line was shot as well.  It's a good idea to have 
that line routed away from the engine(around the edge of the engine 
compartment) to avoid breaking down again due to too much heat exposure.  
Both are cheap fixes.

HTH,
