If you felt confident about your novel when you were querying it before and haven't received any feedback that made you think it needed work before you moved on, there's no reason to panic, but there's also no harm in giving it a read over before submitting.
Also, I found that when my novel was accepted by an editor and it had been over a year since I had touched it, that I was very open to editing suggestions and much more logical about what changes it might need. Sometimes a little separation time is a good thing.
