Oops, sorry. I did have a vague impression that the NAS units may have 
been different ...

With both my SD1 and Rangie, I mounted the amplifier remotely with a kit 
and shielded leads to keep it out of the hot radiator air blast.
Problems ceased.

The grey cell that held the information on the kit I used has since died 
(along with many of his mates), sorry.

The unit is pictured, lower left, here in the Rangie...

I eventually solved all the SD1 problems by replacing the
* Air flap intake sensor
* injector ballast resistor box
by fitting a Haltech digital fuel control unit.

Oh yes ... replacing the Federal flat pleneum with a *real* plenum and 
an attached 4.6L made a little difference as well.
