as per prev post, renewed all the sensors on the cossie, still wasnt right so changed the ignition amplifier on the inner wing and the coil, car started and ran perfect....better than it ever did! was well happy......until she got up to operating temperature and she runs like a bag of poo, like on three cylinders and obv wont boost properly and keeps cutting out! it will start again and run perfect for about ten seconds then go back to runnin like shit! Following has been replaced:

plugs, leads, coil, all engine bay sensors, ignition amp, fuel pump, fuel filter

any ideas?? its a 4x4 saff with a green top engine by the way - totally standard
