Frequently Asked Questions
- What should injector resistance be?
- Most high-impedance injectors measure 11-18 ohms. Low-impedance (less common) measure 2-5 ohms.
- Can I replace just one injector?
- Yes, though some mechanics recommend replacing all injectors if they are high-mileage. It is fine to replace just the failed one.
