As much as I don't like throwing parts at a problem you might
want to try the MAP sensor before the ECU. When it comes to paying
out $450 it's also a good idea just to take it into a dealership
and have them do a full diagnostic on the engine.

I've gone through two MAP sensors and the symptoms are usually
some stubling along with a gutless acceleration except when the
gas is floored or when the engine is running in warmup-mode.

Just for grins, check the O2 sensor lead as it goes up the front
of the block and make sure it's not melted or abraided. This
can cause headaches to the ECU.
