FAQs
Are these injectors suitable for a 2005 Mitsubishi Eclipse?
Based on the provided information, these injectors are listed for 2006-2012 Eclipse 3.8L V6 and 2004-2010 models. It is best to verify the specific engine and fitment for a 2005 model against the interchange part number 842-12312 or OEM specifications.
What is the interchange part number?
The interchange part number for these HDB fuel injectors is 842-12312.
Do these injectors come with new O-rings?
The product description does not specify if O-rings are included. It is recommended to check with the seller or purchase a separate injector seal kit if new O-rings are required for installation.
What does the black color signify?
The black color is a cosmetic designation and does not typically indicate a functional difference from injectors of other colors unless specified by the manufacturer for specific flow rates or types.
Can these injectors improve my car's performance beyond stock?
These injectors are designed as direct replacements to restore original performance specifications. They are not performance upgrade injectors for significant horsepower gains beyond the OEM design.
How do I know if my fuel injectors need replacement?
Symptoms of failing fuel injectors include rough idling, poor acceleration, decreased fuel economy, engine misfires, and a Check Engine Light with related codes.
Troubleshooting
Engine misfire or rough idle after installation
Ensure all injectors are seated correctly and all O-rings are properly installed. Check for vacuum leaks around the fuel rail and intake manifold. Verify electrical connections to the injector harnesses.
Check Engine Light illuminates with fuel system codes (e.g., P0201-P0206)
Double-check the part numbers and compatibility for your specific vehicle. Inspect wiring harnesses for damage or loose connections. A professional diagnostic scan may be needed to pinpoint the exact issue.
Reduced engine power or poor acceleration
Confirm the correct part number was installed and that the injectors are not clogged. Ensure the fuel pump and fuel filter are providing adequate fuel pressure and flow.
