Iv got a 1993 vauxhall corsa gsi and ever since I brought it it's had running problems. It idles fine but as soon as you put your foot down the revs start to die, to get the revs up you have to slowly build them up and then it will get going. Iv changed the throttle body, idle control valve, throttle position sensor, lamba sensor, injectors and loom, ecu, plugs and leads, crank sensor, cam position sensor, AFM and still no change. Their is no ecu light on until it's on a run for about 5 mins. I just don't know what to try next to get it running!!!

did you try the paper clip test then i take it, errr well the only other way then is getting a fault code reader and doing it while the engine is running. but if its clearing when the engine is off it sounds like an electrical problem

Yeah I tried the paperclip idea. Yeah I though it was an electrical problem, that's why I tried to change everything electrical. Now I'm just stuck for ideas :s
