i`ve racked my brains and narrowed it down to 4-5 things 1) i haven`t earthed it properly the bracket i used is touching a painted part of the car body i think? 2) the cable needs properly adjusting 3)the little breather pipe which is too short needs to be connected up (its above the brake master cylinder attached to a cube thing) 4) injectors, when i took the fuel rail off the one of the rubber seals seemed a bit torn. (will have to get 4 ordered when i get a mo) so mabe theres a leak 5) i haven`t connected something/left something loose im going to check each one of theses things before i go work starting with the earth wire. p.s ste could you do some photos as i forgot to do any as i was putting mine on, i want to/want someone to do a proper right up of what is needed, hows it done and any possible problems etc......so anyone new can just look it up an bam! get it done....
