Hi,

I bought recently this nice and comfortable minivan. It has run 113k miles, and is in v.good shape. I am almost happy with is. The engine is the 3.0 V6 type. Automatic, optional 4x4 transmission.
My only problem is the milage. It easily drinks about twice the expected. I thought it is between 20-25 miles per gallon - depending on the driver, but finally it ends up between 10 and 16 mpg (in town or highway). Originally I thought it can be easily repaired and I'll have the perfect car.
I have got checked the engine. The compression is fair in all cylinders, the sparks are brand new, and good type, the air and the fuel filter are new. Air mass intake sensor, ildle switch working well. Transmission, brakes OK. Finally they replaced the oxygen sensor which was really out of order, and promised, that it will solve everything. No change whatsoever. Except the thickness of my wallet.
Maybe somone has already run into this kinda problem and can suggest a sipple solution.
Thanks in advance.
