Manufacturer summary

Original wording in English

This preliminary informational bulletin provides repair information to correct a customer concern of a whistle noise heard from the engine compartment and/or the vehicle runs rough with the service engine light on and/or DTC P0171 set.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
