I was thinking the same thing! maybe the car needs to be tuned at idle around 13 afr in order to work right!Manifolds should be glowing at idle. FWIW I have my idle set at around 13.5:1 as that's what it likes

Yesterday I started it without oxygen sensor at night. I checked the manifold and was slightly glowing that I believe its normal.. If it was at daylight you will never realize that its glowing...
Maybe my eyes gone mad after all this not working situation of the car...
If everything goes well today I will load new file with few tweaks and more fuel above 4000rpm from my tuner! I will keep you posted!
