i have a 94 civic DX automatic that i just put in a EX motor in. the motor ran perfect in the car i took it out of. when i droped in the motor to my car it idles fine. shifts smooth. but once i take it for a spin around the block it will stall and sputter and eventually turn off. i have then changed the fuel pump,ECU,fuel rail including fuel injectors,fuel filter,all fuses and relays,and the coil off of the distruibutor.i have used a p06,a p28 and a chipped out p28 and it all does the same thing,it idles fine and will continue to do so all day. but once we drive it, it will sputter and turn off.we have pumped supreme chevron. all hoses and wires are plugged up also. and it still won't run right. i would really appreciate any help i can get. because i need a car BADLY.
