Have you checked out anything that has been suggested?
Or are you waiting for a 'do this and it's fixed'
I ask because I see you keep asking questions.
Do the 'surging idle checklist '

Any cars I have had do this were due to large vacuum leaks, like forgetting to reinstall a vacuum line or the gasket under the carb was leaking. ( yes this is a FI car)

Any codes? Maybe take it to a shop and have them diagnose/repair the issue.
