car still diseling run on prob

If it's a vacuum secondary, you do not have a power valve back there. If it's a 3310 series vacuum secondary, it eont even have a metering block there, but rather a meering plate that bolts to the main body inside the float bowl. And you do not want to remove the PV from a street car unless you typically either idle the car, or go full throttle. Otherwise you'll need it...
