efi tune up 1.3...

210cc injectors i previously using causes rich AF ratio... this kills my fuel economy and sparkplugs... hence, got my hands on 4g92p injectors... they measures 182cc each... hopefully can achieve close to stoich AF ratio...



changing the injectors are fairly easy... here is step by step on how to change injectors of ur engine...

- unbolt 2 bolts which holds down the fuel rail... becareful not to lose the rubber spacer under the fuel rail...
- disconnect the injectors signal cable... remove the safety pin first...
- pull the injectors out together with the fuel rail...
- unplug each injectors and swap them with ur desired injector... make sure the top o-ring is in good condition... replace it if worn out... worn out o-ring can cause fuel to leak due to high pressure in fuel rail...
- put everything back together in reverse method...
