just an fyi.
i have replaced my rap module what seems like every year since i've own my 95Z. I am also looking for answers. I have notice the rap gets very warm to the touch. I dont know if this is becasue it sitting in a little pocket next to the firewall. I also just replace it a few weeks ago and this one faile from the factory which i am working with my local chevy dealer to have it replaced.
