Originally I had a brown "denso" fuel injector, the correct model for my engine 3VZE (this injector has one hole CC/min-200,OHMS 1.7, lbs/HR-19.6, kPa-290)

i switched those injectors with light green "denso" injectors (he has 2 holes but I'm not sure what is the correct model here is a denso chart: http://club4ag.com/faq_and_tech_pages/Toyota_Injectors_Specs_Data_Denso.html )

I suppose the new injector has a bigger flow rate and I should Increase the amount of air entering the engine.

What do you suggest, how could I Overcome the problem? The new injector

The new denso injector

The old brown injector

The old injector

that's not how it works.
even if the new injector had 1, 2, 6, or 10 jets, it would still be metered for the correct flow rate.

The specs of the new injector show that the amount of fuel is bigger.

I seiches between the injectors, and now I feel that the car is heavier in the bagging of the drive.

Tnx 4 the Quick response

might want to confirm you got the correct one.
the ECU expects X amount of fuel to coordinate with its programmed air/fuel/fire management.
changing one of those will throw off the curve.
