HigH Idle

95 4cyclinder stick shift

When the car first starts up it's at a high idle and takes a long time to idle down what could cause this?

Also While starting up the car, it makes a real loud sqell? just put new belts on. Thanks

check for air leaks and vacuum leaks. check for any stored codes you may have an IAC valve in need of cleaning or replacement

Hey thanks for the reply. How do I check the IAC codes?
