RECOMMENDATIONS
If this condition is identified, it is recommended to disassemble the No.3 fuel pipe sub assembly to
inspect for obstruction and debris in the bank 2 high pressure fuel rail. Debris in the fuel rail can cause
fuel blockage leading to a lean condition and poor acceleration. See below for details:
If this condition is identified, it is important to check for debris in the LH No.2 Fuel Delivery Pipe and
No.3 Fuel Pipe Sub Assy connection port to help eliminate any repeat repairs for customers. Please
create a TAS case and contact TAS for instruction prior to diagnosing or repairing of the vehicle.
Please save all parts and/or details and submit a field report.
