07 Hertiage back fire

My 07 Hertiage Softail runs great but one day it had a backfire thru the exhaust which I had never heard before. After the backfire when I pulled up to a stop light the engine did not want to idle. Had to continue to keep the rpm's up. Started off and no problem with running and the bike did not backfire again that day. A few days later the same thing happen 1 time but clears up. Anyone know what may cause this backfire issue.
 
Does the bike have a fuel module of any sort on it? What mods have been done to it? Exhaust, Air cleaner etc.?
 
If no check engine light, check the manifold for proper tightness to throttle body. Also check and be sure that both ends of battery cables both at battery, starter and ground are clean and secure. Start with the basics first.
