Manufacturer summary

Original wording in English

Service Bulletin - The engine runs rough and makes a rattling noise, accompanied by DTC P0134 or P0135 due to a possible fuel injector leak causing a rich air/fuel (A/F) mixture that fouls the spark plug(s) and causing the PCM to misread the A/F sensor heater resistance. Other DTCs may also include: P0700, P0300, P219C, P219D, P219E, P219F, P0172.

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.
