Need a little more information. Balance rate are off? Too much return? Leaking? Give us something more to work with
If you want to try some cleaners. The GM injector cleaner along with the process is supposed to be about as good as it gets. Otherwise just run some name brand stuff in the tank. Most of the time it only gets you a little more life and you may as well start saving up. Not that it is hard to replace but be prepared to change them anyways

It would be helpful to know what tests were run to determine that 2 injectors are bad. I'm assuming you know which 2 they are? Specific results on the bad and the good ones may tell you a lot. .
only obd codes are for thermostat, but new scanner to me reads alot more need to mess with it a little
