righty... i decided , as to eliminate as many things as possible , as while the head was off, ive done loads of work, (new sensors, puel pump,. chip , map sensor injectors etc ) i thougt i'd put the phase 0 chip, std inmjectors and map sensor back in. fired her up and she runs fine so it is either the injectors that are not atomiseing the fuel (maybe all blocked slightly...?) or its the actual chip itself, unfortunately i got the chip second hand from a breaker wel over a year ago now so woudn't habe though there would be much come back ..??
