Re: [DMCForum] Setting Fuelling - Why does the DMC PRV Hunt?

It sounds like Martin's Volvo specialist is saying that a Euro PRV with a
functioning Lambda system & idle speed ECU doesn't hunt.  If this is true,
then figuring out why is a matter of finding out which parts are
different.
I'm suspicious that the difference is in the Lambda ECU or idle speed ECU.
Maybe DeLoreans were equipped with modules that have a faster response
time
that is a bit too fast.  And if so then it would be likely that Bosch made
other versions of these modules that have algorithms that don't fluctuate
the mixture as rapidly.

I'm curious to know what the hardware differences are between a US versus
a
Euro DeLorean.  Does anyone know if any production DeLoreans left the
factory without cats & Lambda systems?  Or were these parts later removed
because they reduced horsepower?
