Fuel Injectors
Fuel injectors are flow tested and then color coded (RED,
BLUE, or YELLOW) based on upon how much fuel the injector
flows during the test.
When replacing a faulty fuel injector, always replace with an
injector with the same color code. If replacing with an injector
with a different color code, all four fuel injectors must be
replaced with the new color so all four injectors are the same
color.
After replacing all four injectors, the ECU must be reflashed so
the fuel calibration map matches the new color coded fuel
injectors.
Reference Chapter 4 for fuel injector replacement procedures.
