Throwing codes for bank 1 and 2 being lean.

[!!!FAST!!!]

A while back I installed a BBK SSI intake and it started throwing the codes. I remeber someone had the same issue and said they changed out the cooling lines that lay under the manifold with LS6 lines. Has anyone done this and does anyone know about what they cost and where I can get them?

No, and this info may be worthless to ya but it sounds like you have an intake leak. I had an egr leak on my ls1 intake and it gave those codes and random misfire codes too. BTW did the bbk help any??? Ive been thinking of it instead of the ls6 mani. Sorry to hijack...

Yeah, it is an intake leak. Just trying to figure out whats keeping it from sealing right. The only other thing I can think of is the cooling lines that run under the manifold. Someone said they had the same problem and suggested picking up a set of LS6 cooling lines that eliminate the cross over underneath the manifold. I love the BBK SSI intake it's a beautiful look and the performance gains were good. I also added a 85mm BBK throttlebody.
