start with fuel pressure check.

make sure the coolant level is correct. the coolant sensor is very sensitive to this

If coolant level is correct, check for clogged coolant hoses to the cold start valve and IAC.

If the idling speed is too high, which causes surging symptoms described, the idle adjust screw could have worked itself loose. Turn it in to lower the idling speed.
