thanks very much for that info ....its meeting those numbers just checked...cant figure why its coming up with lean on the readings ..says left bank lean ..odd when its not a V engine maybe thats an error..change o2 sensor ..cant hear any air leaks...strange

hi there

that code is for bank 1 running lean. if you have a 4 pot, then that's the 'bank' it's on about! ;)

this might help a bit.... http://www.fordscorpio.co.uk/fuelmonitor.htm
