I have a 94 Volvo; 2.3 Turbo; automatic; approx 165,000 miles that began to stall during acceleration, driving or at idle. Would not go above 35-40 mph or more without barking down. Had a fuel pressure test done and replace the fuel pressure regulator, external fuel pump and fuel filter in Sep 07. The problem has reoccured. Engine check light is not on.
Since this vehicle is equipped with two pumps, do you think the problem could be with the in-tank pump?
