200 10V stumbles, poor mileage

I am apologizing for possible confusion but when I said all the time I meant when all the time when engine is running (or ignition is on). -- Konstantine

OK. Power on all the time (key on), ground provided by the ECU. I was 
wrong in my previous post. If the CSV is activated all the time, 
there's a ground issue, probably involving the ECU, unless some hack has 
been nice enough to provide one, or the wire has somehow grounded 
somewhere between the ECU and the valve. John
