i just swapped my jdm b16 out of one civic a 93 4door dx into a 93 2door ex. motor ran and started fine in the 4door, but everytime i start it up it sputters and dies one time it reved up to 2000rpms then died. the only thing i done is fixed the oxygen sensor wiring. when i had it in the 4door the connector was melted so i spliced the wires. i thought i might have messed up on the black wires because on the sensor side of the connector there are two black wires, does anyone know it would help. need to have it running by tomorrow.
