My maintenance log states the following:

"3022 Lubricate and check engine throttle linkage
All moving parts of the engine throttle linkage must be regularly lubricated with automatic transmission fluid (ATF). Beyond the regular lubrication service intervals, this must be performed after every engine cleaning, and frequently during winter operation when road salt is used.
CHeck the bell cranks, the bearings of the throttle linkage, and the actuator lever for wear and condition regulartly. Check for full operating range."

Ok, I guess that's a start. Just want to confirm the location and how exactly do perform this procedure. I'm sure I can do it myself, and I know it needs cleaning (esp with all of the pedal movement I do!).
