Hello and welcome to JustAnswer!
It's possible you could have an injector wiring issue or internal issue in the PCM but neither are very likely.
The most likely cause for this would actually be the throttle position sensor. When a TPS gets worn it can start to create voltage fluctuations in it's signal. This can cause the engien to die at idle or low speeds if the voltage dips low enough.
It isn't unheard of for an erratic TPS to cause injector circuit codes to set. Sometimes an erratic TPS can be seen with a scant tool but sometimes a labscope is needed.
If you're having RPM fluctuations at idle you can simply unplug the TPS and see what happens. If the idle settles down then replace the sensor.
