Manufacturer summary

Original wording in English

This preliminary informational bulletin provides a procedure to replace the camshaft cover to correct a condition of a whistle noise heard from engine compartment, rough idel, 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.
