Quick question. What are the main symptoms of too big injectors on an overall stock motor? Well, thats besides the black smoke.. thanks

Doesn't o2 sensor feedback adjust injector duration?

Why not just tell us what engine and injectors you're running?

many bad things, too much fuel will wash the cylinders from oil lubrication and promote faster engine wear. Bigger injectors do not give more power. Injector size is matched to the air flow meter.

your injectors should match your tune.

Sorry I didnt give more info. Its an m20b27 I head. I dont know what injectors are they. I believe they are light grey. Im actually waiting to do a turbo setup, thats why im not to concerned with changing them, but im trying to figure some stuff out. Thanks again

Stock M20 injectors are grey, but i and e injectors are different. What ECU are you using?

eta injectors are low impedance. if you used those with a B25 computer, it would fry the injector drivers.
