If you can post what code is being set now, that would help. And as I understand it, the problem now is that the engine is idling low and stalls? The first thing to do for a low idle speed is check the idle valve, they get dirty and cause a low idle speed, and will cause the engine to stall. Sound familiar? Let me know what you find out, based on your information, I don't think you have a bad injector.
