Chuck -

Thanks for the lead. The car has ~43K miles on it. Having owned it
for only 6 months, I've not changed the fuel filter.

My reasoning for the "running lean" assessment is due to the blueing
verse s bronzing of the RB 4-1 stainless header.

I agree that changing the filter is a first option over adding a
resistor of unknown size...
