Idle RPM range
Ok, when I bought my 93 FD the idle RPM ranged 750-1000 but usually stayed pretty much right at 750. Now that I put fuel injector/system cleaner in my car the idle RPM now is 1250 flat and even. So was I just running lean before I had the fuel system cleaned out? What is normal idle speed for a bone stock RX7? I am thinking that large difference in idle range is well...large. Should I be worried?

If your car idles at all you should be happy. Technically, idle speed should be about 750. Mine was 750 before I blew my motor. On the new motor it was in the 1000-1100 rpm range until I got the Power FC, then it wouldn't idle at all. Steve Kan fixed that though, and it now idles at ~900-950 rpm.
There are so many idle problems that I'm fine with it being 200 rpm too high, because it's buttery smoooth
