Just changed the FPR and the loud hum from the fuel pump is gone. THE FAQ here is really excellent.

Have not really driven the car since.

However, after I changed the FPR, and started the car, the idle was hunting between 300 rpm (check almost stopped) and 1200rpm. Any ideas why? Could the new FRP be causing that or just that engine computer is adapting to new FPR?

Next thing I am going to do is to clean the throttle body (bought a new gaskets and a bottle of CRC Air Intake Cleaner.

Is there a picture in the FAQ that can identify all the turbo hoses. Anyone out there sell an entire hose change kit at discount. Just bought a Chilton Manual (absolutely hopeless for 940 Turbos)
