This bulletin is being revised to update the model year to 2008. Please discard Corporate Bulletin Number 03-06-04-030E (Section 06 -- Engine/Propulsion System).
Condition
Some customers may comment on any of the following various driveability symptoms:
• Extended Crank Time
• Hard to Start
• MIL/SES Illuminated with DTCs • Hesitation
• Lack of Power
• Surge or Chuggle
• Rough Idle
• Light or Intermittent Misfire
Cause
Due to various factors, the fuel injectors may become restricted. Extensive testing has demonstrated that fuel related issues are the cause of clogged injectors. At this point, no specific fuel, fuel constituent, or engine condition has been identified as causing the restriction. The restriction causes the engine to operate at a lean air fuel ratio. This may either trigger the MIL to illuminate or the engine to develop various driveability symptoms.
Correction
Fuel injector restrictions, deposits can be cleaned on the vehicle using the following procedure. Under NO circumstances should this procedure be modified, changed or shortened. As a long term solution, and to prevent reoccurrence, customers should be encouraged to use Top Tier Detergent Gasoline .
