I have a 90 Z24 Cavalier with the 3.1 engine. It has a bad set of injectors, and the stock replacements are way too much money through GM. So I was wondering if someone could tell me the flow rate so I could maybe try to find some universals elsewhere. Thanks in advance.

I'm fairly sure thier 19lb injectors. You could go over to the V6 board and ask them, its practicly the same engine.
