The lower manifold gaskets need to be replaced also. The 00M12 tsb is
for upper, lower manifold gasket replacement and also cam chain
tensioner replacement. If you don't need the tensioner, just follow
the tsb as far as lower manifold gasket replacement. That should fix
the cold weather idle problem. Also cleaning /lubricating the IAC is
not a good idea. Since you replaced yours it should last 5 years or
more.
