Great, good thing I haven't drilled my manifold for the MAT yet.    <grin>

Makes sense, heat soak at idle, cools off with airflow.  Hard to understand
GM sometimes.... the V8's use the MAT in the manifold, but most FWD V6 cars
have them in the air cleaner on the header panel or in the intake tract by
the maf (on maf apps).

What ECM are you using?
