I have the same problem... Do you have a CEL? I believe my problem is I need a new TPS sensor.

I would first check for vacuum leaks. Does it go away when it's warm? If so then it could be the IACV or the FITV as well.

vacuum leak probably, to check spray some water on the vacuum hoses, if goes away you have a vacuum leak. Play around with the vacuum hoses to determine which one is leaking and replace it.
