What are the symptoms of a stuck throttle cable?

Introduction to the symptoms of a stuck throttle cable: 1. Throttle cable failure modes include sticking, breaking, wear, and damage, with sticking and breaking being the most common; 2. The throttle cable is too long: the curvature radius of the throttle cable path is too small, with too many turns, causing the cable to move poorly and stick; 3. The grease in the throttle cable's steel wire rope has dried up, increasing the pulling resistance: the throttle cable's dust cover has poor sealing, allowing dust, mud, and other debris to enter the protective tube, hindering the normal movement of the cable. Additional information: The main causes of throttle cable wear failure are improper fixation points, lack of fixation points, or detachment of fixation points, leading to friction between the throttle cable and other components; the breaking failure of the throttle cable is mainly related to its installation method, typically manifesting as bending fatigue before breaking.
I found that when the throttle cable is stuck, the most obvious symptom is that the accelerator pedal feels particularly stiff, like stepping in mud. After pressing it, the car simply won't accelerate, and the tachometer jumps erratically and unstably. It's really dangerous when driving on the highway—if the throttle fails during a sharp turn, it's easy to cause an accident. Once after driving in the rain, the cable rusted, and the throttle got stuck halfway, causing frustrating acceleration hiccups. I immediately checked the cable connections for any looseness or dirt. I usually recommend cleaning the cable groove every few months to maintain lubrication. Never delay car repairs, especially for older models which are more prone to issues.
