Hi, yesterday I drove about 140 miles in my ibiza 1.4 1999 and it used half a tank of fuel. I was driving 70/80 mph most of the way. Also on a morning I start it up before I get in it and when I come back outside I can smell a strong wiff of petrol. Has anyone else experienced any similar problems? Am I right in thinking this could be a lambda fault? Any other suggestions welcome. Cheers, Jon
