High Idle on start up

What is your question?

I was getting high idling while driving not while starting up found that the Trottle Sensor was bad again ,I had replaced the Trottle Position Sensor and Idle Control Valve back in March 2013 due to rebuilding just put everything new. I'm now getting a high idle when starting up after replacing Trottle sensor again. Would it be the Idle valve to again.

You may have a vacume leak causing the fast idle. Also have seen a stuck PCV valve cause this a few times.
