Manufacturer summary

Original wording in English

Some vehicles may experience the Check Engine Light ON with DTC P0171 (Fuel Trim too Lean) and possibly DTCs P030X (Misfire). Vehicles having this concern should use the following Inspection/Repair procedure.

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.
