I would rebuild it. with that many miles your throttle shaft is bound to be sloppy and that can cause the symptoms you are having. it's reativly easy to rebush at home. you need to find brass tubing at your local hobby shop, have access to a drill press, an 11/32 drill bit and some green locktite.

disassemble the throttle plate (file away the exposed screw thread completely so you dont break them off in the shaft), setup in a drill press, use a 5/16 rod for alignment (I bought brass tubing at the same place I got the 11/32 pictured below), and drill the throttle plate. install the bushing with green locktite and reassemble.

Here's how it looks in my garage..
