[200q20v] Vacuum leaks?

[Derek Pulvino]

Brett,

Remember you talking about trying to sort out some stumbling last week by 
looking for vacuum leaks.  You reported finding some and sealing a leak at 
the intercooler.  How'd that change things for you; smoother running at all.

Good idea to use a compressor too, never though of that.

I was also thinking that'd be a good idea to check for leaks around the 
injectors and the intake manifold upon opening the throttle body.  Only 
problem though-is there a point on the cam timing when the path from intake 
to exhaust (be it on the exhaust or intake side) is totally closed on all 
five cylinders?  I'm sure a little thought would get me there, but just 
throwing it out there.  Is this what a leak-down test is?
