What can be wrong with my Pontiac sun-fire 04 for fuel consumption?

Posted by admin on February 18th, 2010 and filed under sun fire | 5 Comments »

The car has 94000kms, and it use to get over 600kms to a tank, but now I only get around 400kms. Can anyone help?

have you moved recently or changed jobs where you have to drive further? my sunfire uses a lot of gas on short hops but my milage almost doubles when i take long trips.

    Have u replaced the air filter or fuel filter? Did you ever have
    a fuel injector flush ? or tune up. it all matters.

    This is a huge change. You may have a leak but check these:

    Tank dented in – holds less fuel.
    Dirty or clogged air filter- engine runs rich
    Emission system malfunction
    Fuel injection malfunction
    Low tire pressure – increased rolling resistance
