It's idling about 300 rpms low

I recently bought my Jeep from an old man close to my house. He said that he had never replaced the MAP sensor or any of the vacuum lines. I can't say that I've done much to fix the problem but I have replaced the vacuum line leading to the MAP sensor. The dash isn't showing a "check engine" light but honestly I have no idea what the problem is. Help?
