Any how to's out there?? Need to change mine out. Anything I need to be aware of? Any help appreciated. Thanks.

I use "heat sink compound" for electronics under it, I got it at Radio shack, not the clear stuff that comes with the ICM.
I use Ac Delco, but have also had good luck with Oreillys BWD, ICM's.
Make sure to not get the wires caught under the edge of the dist cap when reinstalling.
If you remove spark plug wires from the cap when you do it, mark them so they go back in the same spot.

How to, is really similar to this, even though this isn't a Fiero. :

Yep, using heat sink compound (and not dielectric grease) under the module is critical. Otherwise you'll soon be replacing the ICM again.

How did you determine the ICM is defective?
If it is suspect, you might try thoroughly cleaning the spade connection lugs and also the female connector contacts from the pick-up coil to make sure that the issue isn't just a deteriorated connection.
