What does it mean when one of my injectors is clicking abnormaly loud? Like I can hear it clicking with the hood closed. My car also runs kinda rich, I get about 400kms to a tank, with quite a bit of spirited driving. When I used to get close to 500kms to a tank with the same style driving habits.

weird question, its going to be hard to diagnoise without someone hearing it. but are they stock injectors?

 

Yes, there stock.
