I took my fuel rail off today to check my injectors. One of my injectors looked like this:



My car runs fine. I just want to know how much this will alter performance of my car. It idles fine and revs good. I just want to know how bad or degrading it is to a car.

 

I would get another one

 

There's obviously some damage there But if the car runs fine, then I would still try to get another one asap. It's broken for a reason.

 

Its fine its just the plastic sheild, you dont really need it. Id be more concerned with were the rest of it is truthfully.
