Damn, I just got 16.7 mpg on my last trip. (mostly interstate!) It was raining the whole way, that wouldn't make a difference would it?

It is basically stock. (CAI + Dual exhaust)

Anyway, I'm wondering what sort of things could be messed up to give me such poor mileage.

You guys are getting shitty shitty mileage.

I get like 25 highway on long trips, sometimes 27....

Whipster how many miles on your car?

Id say its time for a tune up.

Spark plugs, wires, fuel system treat ment, some fuel injection cleaner, Clean out your throttle body, clean your maf.

Maybe you need a tune. Some sensor could also be out and you might not know it.

I've got 79,*** on it.

Replaced the spark plugs a month ago, just cleaned out the TB

Think I'll have to get some fuel treatment/injector cleaner and see how that works

injection cleaner wont help at all in that case.

you have a passenger side 2nd oxygen sensor out.
Injection cleaner will help your fuel system and injectors.
But your o2's in your exhaust (one being out) will cause you to have a bad idle (maybe) and some bad mileage.

I have seen O2s go bad and the vehicle run super rich too, blow black smoke out the exhaust. An 86 V6 Ranger we had did that.

Bad sensor can make the car go either way, too lean, or too rich....

Also bad O2 can read too lean or too rich and be fine...or the car can be either way and it won't be able to detect it.

If your car is getting bad mileage, more likely it may be running a bit rich....
