82XFire,
Welcome Aboard!
Fast is right (of course). High idle on an ERFI engine is generally due to excessive air, either from a vacuum leak or improper adjustment or maintenance. The usual suspects are all vacuum hoses, intake and throttle body gaskets, PCV valve, EGR valve, power brake booster, and sticking IAC valves.
Another thing to consider is that our old tachs tend to read a bit high, and keep getting higher with age. You might want to get an actual RPM reading from a handheld tach to verify what the dash tach is reporting.
