Default idle problem

Alright guys imma try my best to describe this. Every now and then. When I go to start up my car it'll have a bad miss then if I rev it up high it'll kind of pop and clear up then it runs fine. What could be causing this???? Please help

More info would help, but consider changing the spark plugs and wires as a starting point.

NB1 is notorious for doing this when the coil pack is beginning to fail. Replace the coil pack, plug wires (NGK wires only) new NGK, V Power copper plugs.
