I recently was running codes for bank 1, 2 running lean and my engine started acting up it would surge. It sounded like it was going to shut off. My engine light went off and the truck is still doing it. I have the 5.3 v8. My question is what could it be that would be causing this? It is getting worse now. Could it be fuel pump? Cracked intake manifold? Intake manifold gasket? Please give me some input thanks
have the same problem?

If you have a lean mixture, it could be many things. I would start by looking for vacuum leaks. Check all hoses and the intake for leaks.
