So i have a 2003 Dodge Caravan 6 cyl, 3.3 L, Automatic 4-speed it the mpg on this is 17 city, 24 Hwy but when i drive around the city my gas just vanishes!! It feels like instead of 17 city i am getting like 7. Recently the Check Engine light, i when to the station and they changed the fuel pump. So i want to know what might be the possible problem for my low MPG (even thought 17 is already low) and how can i fix it?Car MPG problem, can any one help?have you have a tune up? a severly clogged air filter and worn out spark plugs can do this also you may want to check the o2 sensor if that doesnt work properly it screws up your air fuel ratio causing you to use lots more gas than your engine needsCar MPG problem, can any one help?well lots could be the cause, but i would look at a few things tune up stuff plugs wires air filter things then I would look at the fuel pressure regulator make sure the fuel pump is working properly. the 3.3 should get a lot better mpg so you have a problem. make sure no leaks on the ground also. check to see if the air hose from valve cover to air box is ok.Car MPG problem, can any one help?A check engine light usually is not an indicator for a bad fuel pump - you may have gotten ripped off...the catalytic converter may be bad, which leads to poor fuel mileage, as well as some of the other suggestions. Also keep your tire pressures properly inflatedCar MPG problem, can any one help?I hate to mention this but are you leaking gas anywhere? 7 mpg would be a world's record I think. If it was running VERY rich you'd be getting backfires.

It would be well worth it to get it checked ASAP with gas prices where they are.Car MPG problem, can any one help?I have a dodge dakota 6 cyl there might be engine sluge or is it or isnt in overdrive?
