LLY motor the LBZ didnt come out till 2006. The major injector problem was with the LB7. The LLY had an over heating problem that was due to the turbo mouth piece. It was fixed with the LBZ or LMM mouth piece. thats already taken care of so dont have to worry about that.
IIRC 2006 had both, depending on the date of mfg.
I know all about the injector problems. It still looms on the LLY. Been there.
2001 - LB7 two sets replacement
2002 - LB7 3 sets replecement
2006 - LLY 1 set replecement
2007 - LBZ none. Sweet engine at stock.
