A high idle in your Bronco can be caused by several factors, including a malfunctioning idle air control valve (IAC), vacuum leaks, or a dirty throttle body. Additionally, issues with the engine's sensors, such as the mass airflow sensor (MAF) or coolant temperature sensor, can also lead to irregular idle speeds. Checking for vacuum leaks and ensuring that all sensors are functioning properly can help diagnose the issue. If the problem persists, it may be best to consult a mechanic for a thorough inspection.
