From time to time, drive the car at higher RPMs to keep the injectors opened for a longer period of time to allow some type of cleaning the injectors.
This will eliminate small sediments which may block the injectors to work properly.
P.S. Be careful, do not destroy the engine
Yeap, I know, so called "Italian tuning" :-)
Speaking about the RPM - what is recommended as optimum RPM for 1.4 engine?
Optimum - meaning best ratio between power and fuel consumption.
And I guess that this engine should not be driven for a long period over 4000 rpm?
