CEL - Lean Fuel both banks
2011 Silverado with 5.3L V8
CEL - Lean Fuel both banks
Long term shows ~29% and short term ~8% at idle
Net zero long/short at ~2000 RPM
I did a smoke test and had a ton of smoke coming out of side of air intake assembly (open port) and some coming out front piece. Did some research and most Silverados have a PVC hose connected to the port. I traced my PVC and it runs from air manifold cover (driver side) to center of engine. I looked all over and didn't see a hose that popped out or looked like it should be connected to the port.
Thanks!
