advance is best for emissions.
advancing timing with same AFR will increase rpm
so the DME is constantly trying to lean AFR and advance timing for best emissions... a back and forth that causes some fluctuations? Are these adjustments from actual o2 readings, or DME trying to hit best operating conditions for emissions
If i remember correctly from the timing table, idle rpm range with low load is 0 degrees.

I can't imagine a coil being an issue at idle, but NOT WOT, part throttle.
