Surging is how it spells, but serging is how it sounds...2 things, I could guess at, given we're just out here together in the ethernet, and you didn't bring the car...well, number one, get you a olde vacuum gauge and measure intake manifold vacuum at idle, and at off idle-like near 2000 rpm's. Reading a vacuum gauge on a running engine can tell you a lot; all healthy engines run with a steady manifold vacuum of 17-21, I live at about 3000 feet above sea level, so I can have a steady vacuum reading of 15 on an idling engine and still be pretty good. If you have low vacuum in the intake manifold, you have too much air in the intake. It's that simple. Too much air means a vacuum hose or manifold is leaking. it upsets the fuel/air mixture for the engine to run as designed.
Number 2. maybe the first thing you should do actually is scan the engine computer for any trouble codes, especially any related to your surging. Write them all down, just you know, prioritize them. It's possible a computer sensor or controller is bad, or also possible that the computer doesn't even know there is a problem. But trouble codes are shortcuts to finding the problem. Well, good luck, keep at it and you'll find it, just like that pot of gold I found...no, i jokes !
