Manufacturer summary

Original wording in English

This bulletin announces availability of reprogramming files to optimize the Engine Control Module (ECM). These new files will stabilize engine RPM and combustion during warm-up due to slight differences in the air-fuel ratio between cylinders causing DTC P0300 to 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.
