An FPr is the "Fuel Pressure Regulator" This is located on the end of the fuel rail right up against the fire wall. It's a bitch to get to on 240s. You have to remove the whole fuel rail.

But since it was mentioned and it won't cost you any money to inspect, pull the fuel rail and check the injector seals. Check for any pinching or deterioration in the rubber. Also check the FPR seal. You have to pull the fpr off and there's a rubber o-ring attached to the inside end. Look at these and if you find any wear, that might be your problem.

Good luck.
