I have a 2001 Honda Accord V6 3.0 Vtech and the tcs light and check engine light keep coming on. The TCS light will go off but the check engine light will remain on. I have taken it to have the code read several times and it keeps saying P0171 bank too lean. Diagnostics even read that code when the light goes off. I have tried fuel treatment in the gas tank and I have heard several possibilites as to what it could be...any suggestions on where to begin? Thank you!!

    You can try this:
    1. Clean the Mass Air Flow sensor. The service manual would tell its location.
    2. Inspect all vacuum and PCV hoses, replace if necessary
    3. Check for a dirty fuel filter and proper fuel pressure

    good luck
