Bad fuel injectors

What are the signs of a bad fuel injector? I get a rough idle sometimes sitting at a stop, it never stalls, and runs fine when I give it gas. I have replaced the fuel filter. I also started using a fuel additive and wonder if that could have done anything.

Thats probably it. YOu need a scanner to do a cylinder contribution test and it will tell you the one that is bad.
