I forgot to mention, this is on an FJ62 so it might be a slightly different setup.

Help... my current gas consumption has gotten worse... I used to run around 5.8 mpg (2.5 kilometers per liter) but now after removing my cats... and after correct timing (7degrees BTDC) was done (finally), I'm down to 3.5mpg... (1.5 kilometers / liter)... So bad.. 
What do I do next? Anything I did wrong? By the way, My dashboard throwing red (coffee-like) error when I plug in my O2 sensors so I left them removed...

That's the worst MPG I've heard of yet, in any Cruiser. How can 3FE run properly without O2 sensors? Maybe you need new ones rather than deleting.
I will check how it can be fixed then... I don't know who bypassed it and when it was done and see how it can be reversed..
I have the same warning light but I don’t have bad mileage. Does anyone have any info on that warning light? I can’t find it in the wiring manual of what it’s called or what turns it on. I removed my cats and left the o2 sensors in place. Perhaps the o2 sensors are bad?
^^^I'd be more concerned about that oil pressure, or is that gauge just broken?
Hahahah. The gauge is broken for sure
