Cart will not throttle down
 

I have a 2020 Yamaha QuietTech Golf Cart with 1500 miles on it. Never a problem on it until today.

When you let off the throttle pedal the cart does not return to a slow idle. You can apply the brake pedal and the cart still won’t throttle down. If you push the gas pedal down and then move your foot over to the brake pedal a few times it eventually will go back to the slower idle as it supposed to.

Not sure if a spring stretched, or if something is hanging up, or something else

Another person drove it without kicking the throttle down to release the parking brake, and it seems to have had this problem since then.

Any ideas on what I should look for?

TIA,

Eric
