Okay, when I pulled the ECU I noticed a couple corrosion or hot spots on the ECM plugs, cleaned them and it's running fine so far.

Okay, good. Let it go for now before you replace the ECM.

I am, but I'm looking at it and one injector is spraying a lot more than the other. What can cause this and what do I need to do to fix it?

That is controlled by the ECM. The injector on time is determined and controlled by the ECM. You may still have a bad ECM.

Driver side injector is spraying just a little bit at idle, passenger side is really spraying a lot. But I don't know which one is spraying the correct way.

A vortec is a multi port engine which has an injector for each cylinder.

You would need a advanced scan tool to monitor the injector on time.

Okay, well I was just doing some research and I come across something that said due to the firing order or timing of the v6 one injector sprays more than the other, is that true? My thinking is that both should spray the same.

No. As usual more inaccurate information from the internet.

It is all ECM controlled based on inputs and strategies.

Most likely not. With 2 injectors, you will be using more fuel.

It's got to be something else. I know it's got some messed up exhaust on it that I'm going to be getting fixed, that should help it some because it has no cats or anything just a thrush exhaust.

As I stated before, this could be and most likely is the ECM itself.
