I think you should send for diagnosis. Maybe the O2 sensor kong out already. Older engines with tired O2 sensors are known to give ferrari like fuel consumption. If the ECU does not receive input from the O2 sensor, it will signal the injectors to spray a rich fuel mixture. This can even caused further problems if not fix. Over-rich mistures can cause incomplete combustion and quicken carbon deposits in the cylinders.

I just changed mine recently. If UMW ones are too costly, try ask your mechanics for compatibles are there are alot of OEMs and plug and play O2 sensors. Bosch ones are good because they are wideband O2 sensor. I don't recomend getting form the chop shop because theirs are also old and used. Unless they can give you warranty to try out.

Previously, I used one from perodua myvi modified to be fitted to my AE111, 4AFE. The wiring and socket are compatible. Works well. Cost RM180 only in Sabah. The one form UMW costs RM703.

1. I think you should try 195 50 15 tire, offset >36 should be OK.
2. External fuel pump should not be a root case to the FC. FC majority are cause by our foot, O2 sensor also not causing much different in term of FC too.
3. If use too cool plug, it will slightly affect the power output too.

have you increase the size of the fuel return pipe???:hmmmm:
your original is 1.3, fuel piping is smaller...

I think you just convert to 20V 6 speed and you want to know more about its secret and your right foot is heavy, this happen to me also. try drive like normal with your full tank till fuel light on and see the FC. Mine normal drive RM 70 is about 350 to 360km. I think you are the one call me about the SE Fuel tank for injection??
