How do you individually check fuel injectors being that theyre over a hundred a piece, and changing them all isnt an option for me.

The best test device to check your fuel injectors for the 12v pulse is a NOID light. The other thing you could do is check the fuel injector coil resistance with an ohmmeter. I don't have the values for your GP model but you can check the resistance of each and compare all 6 of them.
