My car has 140000 miles.
My car has a manual transmission.

This problem is usually caused by the throttle damper out of adjustment on the carburetor that will cause the idle to be too low when you let off the throttle. It is supposed to lower the throttle slow instead of just slamming throttle closed. Have this checked to see if it is working correctly by a mechanic like one from YourMechanic to check to see if it is a minor adjustment or needs to be replaced.
