Hey i brought an ed manual falcon and it didnt run so i replaced the fuel pump now it starts but it runs a little rugh like its got a bad lead so i went and brought new leads plugs and fuel filter but its still rugh so i replaced my injectors with ones out of my ed drag car and still running rough is there a sensor or somthing i have missed that maybe the problem

Map sensor?
Vac leak?
Coil?
Bad earth?
Is it only while idling or does it do it under load?
