^yeah, unless it is momentarily stuck open and takes a few moments to un-stick itself. If it happens every time you do a cold start, unplug the IAC electrical connector and try starting it.

Else, how high do the rpm's surge? Is it dumping fuel - what does the exhaust look/smell like during the surge?
