I have a 2001 Silverado 1500, 5.3L with 123k miles. Recently my "check engine" light has been popping on and off intermittently and I just realized that it seems to go away right after I fill up my gas tank. As the tank gets lower, the light comes back on. I had the codes read at Auto Zone and the computer read "Lean Bank 1 & 2". What are some suggestions for this problem? Should I assume I have a bad fuel filter and start there, or are there other things I should check out first. Thanks!
