Sounds like a bad fuel injector to me. If it is, you'll likely experience the problem getting worse and starting to happen even when the engine is warm. By the way, a hard backfire is capable of destroying the catalytic converter, but I'm guessing what you have is a

"bunk ba bunk bunk" sound. Once the backfire is done, the car pulls hard?
