i have just bought a fiesta rs turbo solid shell tidy car but to be honest the engine loom has been butchered but have managed to get it running struggling to idle and when i try to rev it it splutters and bogs down apparently these parts have been changed ecu,loom,map sensor,idle control valve,crank sensor,co pot,coil pack,plugs,fuel pressure regulator new turbo any help would be great

 

if the looms been messed about with it will probably be that playing up. if the petrol in it is old stick some new in and a new set of plugs and go from there.
