I'm getting horrid gas mileage at the moment. Probably...180-200 to a full tank. I'm starting to assume it's the oxygen sensor and going to take it in and see if thats the case. If it is...whats the best way to go about getting a replacement and fixing it. I know mitsubishiparts has them for $217. Is there a place to get them cheaper? I just had a baby so shelling out $217 for a sensor is not my idea of a good time. haha. But, if I keep this mileage up I'm going to end up paying double just due to gas.

 

 

Universal oxygen sensors for our car run around $90. Get one of those and then solder the wiring harness from the stock one onto it.

 

omg you guys are amazing. thank you.
