Bill, do you have a picture of a CTO valve?

Re: evaporation Cannister
That means you have the pulse air tube type of emissions, right? The
thing with the two tubes coming out of the cat going into the bottom of
the air filter right?
Are you set up exactly like the vac-mcu.gif?
If that is the case, then you have one more place to pinch a line. At
idle pinch the line going into the decel valve from the PCV.
