Hi All, I have just come the proud owner of a S4s. What a great car! Its my second esprit, my previous being an S3 which I had back in 96. Anyway my problem is, under hard exceleration I can get a fuel smell, this only happens under full trottle and for some reason seems to be worse when my driver window is half down, I also got the smell from outside the car when my brother took it for a test drive and excelerated hard from stand still away from me . There is no fuel smell when car is idol. The fuel tanks have been replaced by previous owner so I don't think its these.
