94 Olds idle problem

It has the 3800 engine. Starts and runs fine, but after it warms up it goes into high idle mode. Shut it down and restart and then it idles fine. Any ideas?

would start by having codes checked but sounds like a throttle position sensor problem or could also be a idle control valve problem.
