How to get the car to idle a little leaner?
The tailpipes are blackened and standing back there burns my eyes (no smell, just burnage).
Here's some information:
While idling in drive at 520RPM (sitting still)..
Car warm and in closed loop at 203°
Timing is set at 4°BTDC
Integrator reads 125, BLM reads 113
Here's a graph of my O2 readings:
If you need some other info, just say. If there's nothing to worry about, that too, but I really think it should idle leaner than it does (shouldn't burn my eyes).

try changing timing a few degrees, go a step hotter in plugs, step up 10 or 20 degrees with the t-stat. if that doesn't get you any where you can try colder and lower t stat, but i tihnk that'll make you richer.
