Heavy drinker

[clee]

The 21 has started to drink heavily .The Lambda wiring is knackered but it has been for months so it's not that .I need to take it on a long run and see just how bad it is but it would appear to be doing 12/14 mpg .On the motorway I usually can get 30 and 20 ish around town .
No leaks as far as I can see ,no drips below and injectors are not leaking .
What's left ? Fuel reg ? Knock ?Anyone got the values for the air and water temp sensors ? PH3 car .
