Too rich fuel from fuel injectors

HI, Volker. I tried the Spray test as you suggested on the Chapter 5: Injection valve. I noticed when I turn my key to ignition position (not cranking or start the engine), some of the injectors have sprayed fuel. Is it normal?

Thank you

Hi Danny,

no injectors shall only open when cranking or when pushing down gas pedal. Looks like they need an ASNU treatment I do not know whether that is available in HK. If not, send to asnu.de (Prickartz Consult).

Thanks Volker. I have 6 spare injectors on hand. Will it be ok if I replace it ?

Hi Danny,

I cannot know without testing them. If they have same color, just try.
