Any good Porsche 928 resources/forums...?

[iwrock]

I've reluctantly agreed to help a friend wrench on his 928 and am in need of any good resources or forums. (and after working on it yesterday, have come to the realization that it's probably going to be the death of me)

I'm helping him get it back together after sitting for ~ 1.5 years... We installed a new MAF yesterday, which fixed the issue he was having with not starting/poor performance/poor mileage/stalling, but now is having a weird issue which I'm looking for help on... We're now chasing an issue with it wanting to stall/die when you start it (does it both hot and cold). If you let it idle for ~45 seconds after starting it before giving it any gas, it runs/drives fine but will stall if you don't do this.

So does anyone have any good 928 resources or a good forum? I checked out Pelican Parts 928 forum and found a few things I'm going to check, but would like other resources if anyone has suggestions.
