What causes a high idle in engine?
In modern vehicles, engine idle speed is most often controlled by the idle air control (IAC) motor. When your car’s throttle is malfunctioning, this can cause your car to stall or idle high. Often this is a result of dirt buildup in the air intake. Other times it can be a problem with a cracked intake tube.
