Since your car is an EFI you might want to check your O2 sensor (sa exhaust manifold ni naka ta-od). If guba ni cya you will experience the same symptoms nga rich kaau ang dagan unya kalas kaau gasolina because your ECU will not be able to "detect" if you are running rich or lean... so by default, the ECU runs the engine a bit rich since this is safer than running it lean. It might also take a few kms before the check engine light warns you about the damaged sensor.

Replacement O2 sensors can be bought around 4.5k-5k.

Mostly EFI local cars here in the philippines doesn't have oxygen sensor "O2 sensor".
