Hello everybody!
About 2 months ago I bought a third hand fiat punto 1.2 8v,with aproximately 100.000kms on the clock.And since then,I have been registering a very high fuel comsumption,really poor mpg!I have changed the air filter,plugs,spark plugs and even took it to a diagnostic machine to check for faulty sensors,but the ECU is found to be in great shape,no faulty sensors whatsoever.The mechanic tould me that it was burning all the fuel properly,there were no CO2 problems with the exaust meaning that there´s really nothing wrong with O2 sensors.I also changed the clucth 2 days ago,but all in all,mpg remains the same.I drive like a very old granny,no town driving,just 80 kph on freeway,and going very easy on the throttle.tyre pressure is ok,but 175/70 are fitted,instead of the 155/60,can this be causing all the problmes?
I´m registering an average of about 9litres per 100 kms,not normal.
And the car seems to be pulling fine,no trouble at all.:bang:
A friend told me I could have a ruptured exhaust,or fuel line,but theres no smell not even noise.
Please excuse my english,I´m from portugal!
hope someone can help me.
many thanks!
p.s.:altough having this problem(and some others),I just love my punto
