Mga Papi,

My father-in-law's pathfinder pickup just recently had its injectors recalibrated. Parang it is done once every x number of years daw as part of regular servicing.

Now my question, how about the injectors for EFI gasoline engines? One mechanic told me before that it is not needed for gasoline engine vehicles. The ECU takes care of the spray quantity coming from the injectors. Hence, it does not need to be serviced, unless kung talagang may tama.

Out of curiousity lang pmga papi, could someone please elaborate on this?

Thanks.
