1992 240 RPMs dont drop after letting off gas

I was in an accident about a week ago, and after three days of work and a sale at the local pick and pull, the car is looking like nothing ever happened, and there are only a few symptoms left. One such symptom is the throttle.

When I use the gas pedal, the RPMs rise normally, but when I take my foot off of the gas, the RPMs stay at that same level. I am only able to bring them down to the normal idle speed by pulling the pedal back up with my foot. When I do so, the idle remains stable at ~770 RPM.

What might be causing the problem and how might I fix this?

Upon further examination, the RPMs do drop, but it takes a substantial amount of time. It is especially slower at lower speeds.

Check the throttle cable linkages and the return spring is operating corectly.

I just sprayed the mechanisms around the throttle spool with some WD-40 and (with the car off) pushed the pedal down to the floor and up several times. The throttle is more responsive than ever, turns out these guys get a bit sticky after 20+ years. I did check on the linkage and the cable, it seems to be working fine.

Maybe I just noticed it while I was troubleshooting, maybe its because the car was sitting for over a week, maybe the linkage was bad and I'm just battling symptoms (I'll know soon enough). For now though, the problem is no more.
