thanks to everyone for your input, it was all valuable.
I ended up having to pull the alternator to get to the lower bolt, I just couldnt get enough wrench on it to get out.
GOOD NEWS!!! The Hemi breathes fire now
The EGR must have been going bad for quite some time. In the time that I drove it to get the computer to relearn, my MPG is up about by about 4.
Locking it in at 30mph, it just humms right along, no more searching for the right mixture or reving.
Best $39 I've spent on my Jeep!!!
