I agree that it seems to be a vacuum leak, but I can't find anything.

I removed, cleaned and replaced the Idle Air Control Valve, no help. I disconnected the IACV and it made no difference.

I checked for codes with the on-acc-on-acc-on trick and got
P-0508
P-0633.

which don't seem to be listed.

I might try replacing the IACV.
