bad fuel injector

[stillmatick]

Can bad fuel injector cause random funny idle?

All hoses are new,replace o2 sensor for the hell of it,no crack on intake boot,icv still works,clean icv and mass air flow sensor. There is no air leak what so ever.Most time the car work perfect is just that rare random funny idle i get here and there. To me I assume is the fuel injector. Also there's no cel light when random funny idle start.

Fuel pressure/failing fuel pump can cause odd problems.
