Injector 2 is goosed and wasn't properly recoded. It can be very hard to reprogram the injector if there is a fault code attached to it – I pretty much guarentee that's the route of your problem.
You ideally need to get a new injector and them all properly recoded. Having said that, when one goes, the rest are always close behind.
Get the alternator sorted too, that can cause all manner of issue, and can damage the ECU, and other components.
