ok it looks like I need to replace a bushing on the throttle body somwhere. However I don't where on the throttle body it is located or anything. I looked in the haynes repair manual for instructions on how to remove/replace the bushing and I can't find any. Please help.

You're not likely to find a bushing installation procedure in any serviec manual, let alone a Haynes (which seem to be among the least informative, but cheapest).

The bushings are at the ends of the throttle shaft, and require removal and disassembly of the throttle body, drilling the throttle shaft bores, pressing in bronze bushings (preferably oillite bronze), then drilling and reaming the bushings to the correct finished size. You'll also need to mic the throttle shaft for wear, and be prepared to trash the whole TB and replace it if the shaft is worn excessively.

IOf you don't have the equipment or means to do that, you may want to find a good used TB in a wrecking yard and clean it up for installation on your engine. Of course, you'll probably have to look through the selection of TBs to find one with little or no shaft wear.
