Hello my name is XXXXX XXXXX thank you for your question.
Did you try cleaning the throttle chamber?
no have not done anything it just started 3 days ago
When ever I get Start stall issues with these older Sentra's most of the time a dirty throttle chamber is the issue.
Try getting some carb cleaner and a old tooth brush and a clean rag
and spray and scrub clean the throttle chamber and whip down with the rag
Give that a try and let me know how you make out.
thank you will give it a try
