I'm barely getting like 200-250 miles per tank. Plugs/plug wires are new, prolly should replace cap/rotor too cause I have no idea when that was last done. I sure hope after replacing the o2 sensor I get good mileage again cause 200 miles per tank on a slow ass 4 banger sucks.

 

anyone?

think a clogged air filter can affect mileage this significantly?

 

when did you notice the milage going to sh!t? catback exhausts, new rims, under inflated tires, and a dirty air filter will mess with your MPG's.

 

it's been pretty consistent for the last month or so

 

Fuel filter?

 

damn! that's a possibility too. I don't like that one cause it's a pain in the arse to replace

 

If you do need a new O2 sensor, try here;

wouldn't the 02 sensor throw a check engine light if it was bad?

 

how do you get to the fuel filter...where is it at? 5th gen of course

 

Somewhere below the Intake Mani, it's a pain in the ass to get to from just looking.
