Might be a bad distributor or a bad injector

more details might help, such as what procedures you've done, what you've tested, what's been ruled out, and the full state of the car as well as anything that's changed. The more you can tell us the better. What you've got there is pretty thin info, hard to make any good decision or suggestion from it. At this point it's basically going to be me quoting an entire chapter of the FSM since there's no good place to start.
