P0171 Lean mixture fault diagnosis and repair. In todays video I diagnose and repair a vacuum leak from the cam cover on a Chevy cruise. A common issue with this vehicle.
Changing the cover will not fix your problem. It is the diaphragm inside the cover was destroyed. Go to cruze forum, there is a detailed discussion, a guy even sell a kit to deal with it. By only change out the cover, the diaphragm will be bad in six months, you will be in square one again.
