Hi..I´m having a trouble with my ´02 2.0L Trajet.....Earlyer this year i put in an "new" engine (from Sonata)..And the car used 16L/100KM (2 much)...now last two months it has been 18.7-19.5 L(H-****)...does someone know what sensor might be gone bad or even what else it may be...

well theres a few reasons an engine starts sucking more gas.
it does seem a little high, i just checked out the fuel consumption ratings.

start with the basics: spark plugs and wires, any ECU codes, brake rubbing, dirty throttle body/intake, transmission badly needing a fluid change, bad o2 sensors, etc.
