Hello,
An engine can surge for a number of reasons. It could be due to a vacuum leak, faulty mass air flow sensor, issue with fuel pressure.
Here is a helpful guide:

Many times, the engine can surge due to any engine management system sensor. Which will typically turn on the check engine light.
Is your check engine light illuminated? If so scanning and retrieving the code(s) can help with the diagnostics.
