240 RPMs stay high after releasing throttle

[Maximum Turtles]

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?

Remove the cable from the throttle spool. start engine. rev engine by hand. If it returns to normal you need a cable. You can try lubing it with WD 40 and compressed air..... Its likely stuck after 20+ years ( mines 38)

I went ahead and lubed it up, its working fine now! Good call, thanks for the quick reply.
