I have an 84. How many rpm's is the surge? Do you know when the TB's had been balanced last? Have you checked for vacuum leaks?
Check out the Crossfire Injection Vault @ http://www.crossfire.homeip.net/ the folks there are quite knowledgeable.

Re: 84 surges at idle (parrotguitar)
It's caused by minimum idle speed being too low. Most commonly caused by buildup of carbon in the throttle body, the throttle bodies need to be cleaned.
Take the cleaner off and use throttle body cleaner and a tooth brush to remove all carbon from the throttle blades.
Unless youve had some linkage problems or someone goofing around with the throttle linkage, it probably does not need to be balanced.
Oh...and the CFI forums are pretty good too.
