Under the air cleaner, on a "joint" of the throttle linkage (sorry, I don't know engine terminology) is your Thrust Cut-Off Switch -- a roller switch very similar in appearance to the image below, except it will be white or tan. (The image below is NOT the actual switch.)
If that switch fails, your RPMs will stay high when you lift your foot from the accelerator. It removes in 2 seconds and costs about $50.00 from the dealer.
You cannot visually determine if it is faulty, nor do so by hand. If the linkage it depressing the switch arm, and your RPM is not dropping, the switch is broken.
