SOURCE: 1987 chevy r20 carb with electric fuel injection

I would check the wires that make the injector function to see how much power is going to them (using a multimeter). Now check the wires on the injector that is not working and see if you have power there. If you do then you have a bad injector. I don't think you do since you said that you switch wires and you are getting fuel at that injector. Check your wiring harness for shorted out wires. It doesn't make sense for one side to be working and the other not to be. I don't think it is a problem with your ECU, but it may be. See what colors the wires are going to your injectors and trace them back to the ECU, a wiring diagram would help. You need to check to see if you are getting power from the control module to the harness. I believe, however, you are experience a shorted out wire somewhere in the harness. That is where I would start. If you confirm you are getting power to the control module, but you are losing it somewhere in the harness it may be easier to just run a new set of wires instead of tearing apart the harness.

1987 chevy r20 rough idle


Well, the computer is supposed to open the IAC to keep the RPM above 600 or so depending on the load on the engine.
If you have voltage and ground for the IAC it should raise idle speed to at least 1100 when you first start the engine cold.
If that is not happening, I would look for carbon build up in the throttle body. You can apply voltage to the IAC and open it to see if the air passage is open too.

It may sound obvious, but have you changed your inline fuel filter? if so, try a"fuel system cleaning" next.  available at most oil change garages. It runs anywhere between $60-120 and does a pretty thorough job of flushing out the fuel injectors and cleaning out of all the fuel delivery components. I've seen some amazing results with the flush.
