CHEVY ENGINE SURGING

1999 Chevrolet Silverado

Engine Mechanical problem
1999 Chevy Silverado V8 Four Wheel Drive Automatic 141000 miles

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

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.

Let me know what you find.
