Frequently Asked Questions
- Do I need to replace all injectors?
- No — only replace the one that has failed. The others may be fine for many more miles.
- What does injector resistance tell me?
- Compare to specs (typically 11-18 ohms for high-impedance injectors). Out of range means the injector is bad.
