Gas mileage problem

[mrflex96]

I have an 02 4runner that was in storage for 3 yrs and brough it out about 2 yrs ago. As soon as I got in it I knew it wasnt the same. I have done alot of maintenance to it, change the plugs, wires, MAF sensor, O2 sensors front and back, oil changes, I have had the injectors cleaned and I had a K & N filter which O took off.. Its not leaking any fluids, no warning lights come on, no leaks. I was wondering if anyone can give me an idea on what to do or something that I missed to do? This spring I am changing the trans fluid along with the diffs.

What are you getting for mileage?

What are you getting for mileage?

x2

put really small tires on it, avoid the city, no roof rack, no visors, remove the rear seats, no passengers.

after that you should be good.

Did gas sit in the tank (and the rest of the fuel system) for the 3 years without treating it with fuel stabilizer? Gas will turn into laquer when it sits for a while, it could have gummed up your lines.

If it's been sitting for a long time, and then you start it up, a combo of bad gas and bad seals could result in a bad burn - thus clogging up the cat a lot faster.

It's a long shot but exhaust is sometimes overlooked.

Many things it could be...

x3 though too, what mileage are you getting?
