Hi there. Check the distributor or coil packs to the vehicle. The surging would most likely be caused by the electronics getting old and causing a delay in the spark ignition. I recommend replacing the spark plugs and wires and then retesting for the condition to reoccur. If you need further assistance with your engine surging, then seek out a professional, such as one from Your Mechanic, to help you.
