grampafunk,
hey thanks for referring me to the g2ic website! I found a post on there on "DIY main fuel relay fix". Right down my alley! I just reinstalled my cleanly resoldered relay -- we'll see if this helps me out with my problem.
I'm still not convinced that the relay could be the cause for my low idle (about 500rpm or lower).
I will probably have a chance in the morning to check out my fuel filter -- I bet that (old fuel filter) might be the contributor though...
anyway, thanks again for letting me know about the site!
