What do you think it could be? The check engine light is NOT on. Only when you start it is when it idles up and down but then it warms up and its fine and runs like normal.

get some carb cleaner and spray it around the intake manifold to see if the idle changes. It'll be difficult to hear idle changes while it's surging up & down so pull the IACV, it should bring it down to a steady RPM
