I would definately agree.
And 'careful searching' is certainly correct. I've found you have to be very accurate and sometimes very clever to get certain threads to be found in the search. Some have been extremely hard to find (maybe I'm just search retarded...

) but still I think an archive of the very best and informative threads is a good idea.
Heck, I even started one such possible thread

, which Nutz contributed VERY good injection system info and diagnoses, among other great info from fellow forummers.
