ok so i swapped my 93 coupe motor for a 95 due to one of the rods broken by the previous owner.
now here is my problem; when i start the car it revs up really high like 4k rpms, then drops and the car dies. i changed the plugs and wires, i timed it but i think i did it wrong. also i removed my emissions. and when i unplug the other emissons it makes no difference.
so im asking what coud this be??
