    Changed my fuel pumps to the new improved ones . No leaks, car runs great .
    I keep getting a P1126 code on my Launch “ Fuel Self Learning (B2) : Lean “ . Clear it , comes back on after 5-10 miles. Even tried disconnecting the battery . Is it truly going through some self learning process?
    Suggestions ?

    I am interested did you install new fuel pump assemblies or new fuel pumps in the existing housings. If you did not have issues prior to the fuel pump replacement I would check the fuel pressure under all driving conditions. New "improved ones" always makes me nervous.
