5.2L running lean
I just bought this truck a few weeks ago and it was running great... After a few days of driving however the check engine light came on and a code reader reported it as running lean. I took it to my master mechanic uncle and he said that looking at the trucks info it was a leak in the intake gasket. Intake gaskets were changed and the code went away for about an hour. Then the light came back on and I can smell the engine running lean... Any ideas what this might be?
