I recently purchased a 2003 CRV EX with 165K (AWD, Automatic) and have been getting it road ready for my daughter, which has been more of headache than I thought. I had to replace the Catalytic Converter and tires to get to pass inspection and that was $$$$. It is mostly ready now, although I still have a P1457 evap system code that I have yet to resolve.
One of the things I am noticing is that it seems to be using a lot of gas. I recently filled it and after only 100 miles it is down to a half tank. It was all around the town driving, but think it is supposed to get better economy that. I am concerned that there is still something not right with this engine. I was wondering if replacing the Cat can effect mileage, -whether there is a learning cycle or something. OR is the P1457 is killing my mileage.
I ran a bottle of Techron through the gas and changed the air filter, but have not done the spark plugs. (Honestly after the repairing Cat my budget is a bit blown out.)I did notice that one of the rear bolts that is embedded into the aircleaner housing is missing and the airbox is not able to be tighted down in that area leaving a bit of gap. Not sure if that is a problem or not, probably not since people use those exposed cone filers all the time. Anyhow it would be great if someone could give some advice or just point me in the right direction.
