It only has two! 91 Astro but year of engine unknown. Its first Gen throttle body fuel injection system. It looks like a carb except has TWO spray nozzles on top that only spray wide open?

I've never seen that kind of set up, it can't be from a 1991 anything., good luck, maybe someone has seen this, not me. When you said carb and injectors I figured you were just joshing around, I guess if you are looking at it then I guess it exists.

Most likely you have a shorted injector driver in the ECM, when that happens the injectors go wide open, if it isn't fixed soon it will fry the injectors also.
