A vacuume leak at the intake manifold or vacumme hose can cause a high idle. On carbuerated vehicles the idle adjustment screw may be set to high. On fuel injected vehicles, the Idle Air Control(IAC) circuit or valve may be faulty. On newer vehicles you may be able to get a trouble code to help pinpoint the problem. Chris
