Hi Team,
Well solved it I guess. Kind of. I turned the cog in the afm clockwise 8 turns ( leaning it out). The afm mixture screw to 4 turns out. Finally got the the o2 sensor to fluctuate between 0.2 and 0.7 volts. Previously I couldn't get it to move off 0.9vs. 0.9 v being rich! I think it was so rich it was out of the range of the o2, hence taking such an adjustment to get afr near ideal. So either PO changed the afm cogs or I don't know. What else could make it so rich?
Anyway, now my idle is perfect. I can remove o2 connector and idle stays as is. I rev it, and it settle at 800 rpm and doesn't move! So happy, was pulling hair out to try get it to idle well.
