If the car seems to be surging please start with checking the coolant for proper level and with it running open a bleeder on the upper radiator hose to release air in the system. After that check for any vacuum line leaks. Let me know.

Suggested Repair

Check the coolant level and, with the engine running, open the bleeder on the upper radiator hose to release trapped air. Then inspect the vacuum lines for leaks.
