How can you check your fuel injectors?

on your car to know exactly which one needs to be changed? I have a 95 Buick Lesabre and its in need of new fuel injectors. They are expensive to repair, and would like to find out which one is bad instead of changing all 6! I know its the injectors b/c the repair shop stated its the problem.|||Well Since it is a 1995 you can Need an ODB 1 Diagnostic Computer, But here is what you can do You can go to Autozone and they will put the computer on it and check the fault code in the computer just to make sure what they tell you is correct , and you can have a Cylinder Cut Out test done which will Take Power from all the Injectors till you find which one isnt hitting So say you Cut power from #1 Injector and the Engine Starts to Miss Hard then you know its a Strong Injector if it doesnt and doesnt change the way the engine is running this thats your fowled injector, Another way is to Disconnect the Connectors on top of the Injector Till you find out which injector Doesnt Hit!
