We have a 1999 honda accord EX 100000 miles. The check engine light keeps coming back on the computer code we keep getting is p1457. We have gone through all the tests in the Honda Book and replaced the O2 sensor. Do you have any suggestions?

That code does not usually point to the O2 sensors but refers to the emission side of the fuel system that usually has a charcoal canister and a few sensors. The problem could be a vacuum leak in the fuel system. A very simple cause of this can be a badly fitted gas cap or a leak in the gas cap.
