| If it is a LB7 (8th digit in vin is a 1) then it is probably a bad injector. The injectors in the LB7s are covered under a 7yr 200000 mile warranty. If it is a LLY (8th digit in vin is a 2) then it may be the injector wiring harness. The have been known for the wires rubbing a through and causing problems.
