mga masters,
i mean to ask you a rather silly question because i have been planning to buy an eccs nissan for my next car. the question is, do EFI cars have A/F adjustment? may idle din ba? or wala na? maybe the cars computer will automatically adjust itself? forgive me of these questions because im totally new at this.. thanks for the relpies in advance... ingat po...

Fuel quantity is adjusted by varying the on and off times of the fuel injectors.Last edited by oj88; September 11th, 2010 at 10:46 PM.
