1986 Jaguar Vanden Plas 4.2L Poor Idle Quality, Poor Fuel Economy, runs pig rich
Hey Jag techs, I found that there's no fuel return going back to the tank, if I disconnect the return line it runs fine, I tee connected a pressure gauge on the return line and it builds pressure (45+) then the motor starts running pig rich. Can anyone help me...
