What size engine?
Disconnect the IAC valve with the engine running. Does the engine
speed drop? If so look for a problem in the computer system, a trouble
code scan and diagnosis will probably be needed. If the engine speed
stays about the same after disconnecting the IAC valve look for a
mechanical problem such as a binding throttle linkage, sticking IAC
valve or a large vacuum leak.
