APPLICABILITY:
LEGACY, IMPREZA, AND SVX WITH EGR

SUBJECT:
FUEL INJECTOR REPLACEMENT

If you should receive a customer complaint of a Legacy, Impreza, or SVX being difficult to start, after a long cool down period (such as overnight) under extremely cold temperatures and high relative humidity, it has been found that under these conditions ice may build up at the tip of the injector and cause a no start or hard start condition. OBDII equipped vehicles will illuminate the MIL and exhibit trouble codes, P0301, P0302, P0303, P0304 (P0305 and P0306 for SVX).

A newly designed injector is now available to prevent the condition. All injectors should be replaced with the newly designed injector as a set of 4 (6 for SVX).

DUE TO THE FACT THAT THIS WILL ONLY OCCUR UNDER SPECIFIC DRIVING CONDITIONS, AS DESCRIBED ABOVE, REPLACEMENT OF INJECTORS MUST BE PERFORMED ONLY AFTER CONFIRMING THE CAUSE IS RELATED TO THOSE CONDITIONS.

Please note :

1) The repair procedure outlined in this bulletin is only to be applied on an individual complaint basis and to be supported by a fully documented dealer repair order describing the customer complaint and any trouble codes present.

2) Removed injectors will be remanufactured. Therefore, all injectors must be handled with care to ensure proper core credit. Refer to Service Bulletin # 09-33-95 for proper removal techniques to avoid damage. Take care during storage and shipment to avoid damage. When returning injectors, be sure to package each injector in its original box. If the original boxes are not available, be sure each injector in a shipment is individually protected.
