New rails, lines and HPFP. I see it alot where they come into work and have a fuel trim balance code set for one bank. GM used to have us replace all injectors on a bank if one was bad. and it fixed the problems. These injectors can give you real fits! I would for sure replace all 8 and make SURE to replace the high pressure lines going from HPFP to both banks. dont reuse!
