Curious why you think it's the injectors. From reading it looks like you have at least a wiring issue with the o2 sensor.

What sensor on the cylinder are you referring to?

do what JFP suggests. Very much doubt you have a bad cylinder as you would have more problems and noises if so.

To test the injectors the best thing to use is a NOID. It will tell you if an injector is getting power. You can also bench test each injector to see if they at least work, which I bet they all do.
