check the fuel pressure, it may be high.
the other option is the fuelling is massivly rich, so when you shut the pump off the pressure in the line drops, so the car runs ok ish untill it runs out of fuel in the line
the feed out of your reg is the return line

hi james, yes the car is over fuelling big time iv had to get a new L8 green label one this time my old one was red label, do i need to get a lamaba sensor, see im not sure if i hav the correct vacum pipe on the 3 bar map sensor either could that cause it to over fuell badly, cheers hugh ps James could you pm me your email address, as iv'e still not sorted that thanks

maybe the carbon canister,
the car will run on the 55s with a greens chip but you will not be able to use it or run it for long periods like it, as the fuelling will be miles out.
if you want a 55s chip give us a ring. we do cracking 55s packages
you dont need a lambda, but its well worth while for the price of a sensor, especialy if you are getting a new chip
