have you checked you fuel pressure regulator as some times as you rev the engine the fuel pressure will over fill the bowl or even simpler your fuel bowl shut valve may need re setting

Fill the tank up but do not top off.

Ran the trunk for 15-20 minutes on the highway and recheck the fuel surge condition at 2500 rpm.

If it stop surging then you has a weak fuel pump.

Change the fuel filter will also help.

Also check the fast idle setting.

If everything checks out then set a smog check appointment in the EARLY MORNING.
