Running Rich

[Roga]

Hi everyone
My 1uz runs a bit rich and am wondering if changing the O2 sensors for another type or somehow tricking the computer will help

It has the genuine loom uncut and the genuine computer (UCF11)
Anybody tried this way ??

Thanks
Roger

Pull the plugs... is one cylinder running rich and causing all the smoke?
