I efiled Fed, NY and NJ tax returns at the same time. Both Fed and NY were accepted on the same day. NJ is still in pending status after 6 days. Is this a common delay people are experiencing from NJ?

Yes, NJ is slow. One year, it took 10 days for my state return to be accepted.

Much appreciate your response, SweetieJean.  

I'm having the same issue.  I filed Fed, NY and NJ at the same time on 4/15.  Fed and NY accepted on the same day and NJ is still pending after 4 days. It's past due date now.  Shall I be worried?  In the past few years, NJ took one extra day for me.  When it took 10 days for you, was it accepted after the deadline?  

Thank you!
