just check the the injector thoruoghly.funny thing about this is.my car gave me 2 ecu codes.the same 16 u got for the injectors.and it gave me a 1 for oxygen content.its weird.....but that was the first time i got the fuel injector code 16 from da ecu.it did trip an engine light.but once the car is shut off.the check engine light is no where to be found.....i think i jus gotta check my o2 sensor.and see how that bad boy turns out......but check for loose wires and/or clips on the injectors
