Fuel Pressure Regulator changed now no power.
I just bought a 2000 S40 1.9 Turbo. It was idling very rough and died when you turn on the AC. The car ran great at speed. I changed the Fuel Pressure Regulator and now it idles fine but when I touch the accelerator it starts to cough and sputter and will not rev up. Not sure what to do next.

Thanks for the response! The Fuel Pressure Regulator came as a complete unit that included a new S shaped hose. Based on your recommendation I went back and made sure the metal line on the manifold wasn't clogged. Still no change.
So far I've changed the Coolant Temp. Sending Unit, the Mass Air Flow Sensor, Fuel Pressure Regulator and cleaned the Idle Control Valve and it still will not rev. beyond about 1200 RPM. It Idles really smooth at about 900 RPM but bogs down badly when I press the accelerator.
The Check Engine Light is on but the scanner I used showed no code. I've ordered one that says it will read vehicles from '99 and on.
