I'm no mechanic, but unless the spark plugs are made ENTIRELY of platinum
instead of just the tips - I'm guessing about $1,900 of that is the cost of
replacing the converter.

Maybe replace everything (including your mechanic) except the converter
first and see what happens. I thought I read/learned once somewhere that a
fuel failure at the top end can damage the converter - however, I'm trying
to understand how that would affect the engine, as it's just for the
emissions. Does the engine read the emissions AFTER the converter and
adjust itself...?

hm.
