clio 182 poor performance and using silly amounts of fuel :(

[stoney182]

Have plugged it in on the diagnostic systems at work but no faults stored, no engine noises or any thing just seems to be flat like if a mass airflow sensor has gone down on it or such like.

is there any thing that is a commonly known proble?
any help verry appreciated
cheers

what system have you plugged it into mate? seems a bit strange. When you say silly amounts, what mpg you getting?
