Did you just unplug the electrical connector? If that changed anything, then I think your CSV is mis-wired.

The CSV should have zero effect on the car while it is running.

The valve needs two things to open up. It needs power on one pin of its connector, and it needs ground on the other pin. The ground is provided by the thermo-switch, which grounds its input if the temperature is "low enough". (How low? Not sure.) The power is hooked into the yellow wire that goes from the key to the starter. It only gets power when the starter motor is cranking. Not at any other time.

So the CSV should open up only when the starter is cranking, if it is also "cold enough".

If you mean that you clamped the hose going to the valve and things got better (or worse!), then I would say that the CSV is leaking fuel.
