Alright so here's what I got going on. The car runs fine and all for the most part. However, idling at a red light or a stop the car will idle fine and then all of a sudden theres a hit which feels similar to a miss fire or backfire. I've changed the plugs, wires, cap, and rotor button. I also dumped a bottle of sea foam in the gas tank thinking maybe crappy gas. I'm at a loss at this point and am looking for pointers for other things to look at. If anyone has any ideas please let me know and reps will be given.

Thanks!
