Hey Everyone new to the forum Just picked up a 1997 Discovery XD.


I am having issues pulled codes said I had #2,#7 injectors not firing clogged Y pipe. and it falls on its face when you hit the gas at idle runs just fine but when you hit the throttle it back fires and wont even go.


I have changed the y-pipe replaced both injectors checked the fuel pressure at the rail it is 38psi. I have the 4.0.
