Sounds like a vacuum leak. I would check all the hoses and fitting going into and out of your intake tube. Hopefully for you all it did was blow a hose off the intake. I had that happen once last year as well. It blew all of the vacuum lines off of the intake tube and plenum!

It might have damaged your maf sensor when it back fired.

unplug the maf and see if the idle improves
