It's a 1 series,petrol,its done 90,000 miles,I don't have a clue about cars!!, but when u start it,its tryes and when u put foot on accelerator it just dies out,until u keep trying then it just starts .I don't know what it is the problem David.
Thanks for your reply David, iv had the pressure sensor replaced and its still having difficulty starting, after 10/15 attempts it starts,but isn't performing properly.
