Thanks for all the feedback! On another 3 I just sold, I had the same issue=
with mechanical fuel pump and cam lobe and replaced with low flow electric f=
uel pump. Fixed problem perfectly. This car has electric fuel pump. I turn=
ed two more flats rich and also forgot to top off the dampers with oil. Tha=
t did the trick. I could probably bring the idle down to 750, but then the h=
ood vibrates with an awe full noise at the latch. Haven=E2=80=99t sorted th=
at yet, but it doesn=E2=80=99t do it with idle at 900. =20
