A high idle in a 1991 Acura Integra can be caused by several factors. Common issues include a malfunctioning idle air control valve (IAC), vacuum leaks in the intake system, or a dirty throttle body. Additionally, a faulty coolant temperature sensor or an incorrect adjustment of the throttle cable may also contribute to the high idle. It's advisable to diagnose the specific issue through inspection and testing of these components.
