You may have missed it, but I recently put out a message to the effect that I
was producing alot of black exhaust smoke when I was in either first or
reverse, the only reply I had suggested that I could be running rich. Could
this faulty lead be the cause?

I replaced the leads about 9 months (4000 miles) ago with Bosch leads from my
local auto-parts store, is that quick for breakdown, and could something be
causing it?
