I've had this check engine light for about a year. The code says that the O2 sensor is reading lean. Apparently there are a TON of reasons why this might be the case, and no mechanics want to bother with it. O2 sensor might be messed up or the exhaust might really be lean due to something in the engine?
What should I do? My gas mileage is still incredibly high (40-45mpg, 2000 Toyota Echo 108K). My fuel filter might need replacing though. Could this fix the problem?
