    Has any one else experienced a knocking issue with there 5.3? I own a 2005 Z71 with 87000 miles on it. I started knocking so I immediately changed plugs and wires. Quieted it down some but it now seams to be coming from the lifter area. I havent experianced any oil pressue drops or increases. The only code that comes up is Bank 1 and 2 lean. Hopefully someone else has experienced this and can point me in the right direction.
