every now and again my car, when starting, will only run like it is running on 2 cyl. If I hold the pedal to the floor it will eventually come out of it. This happens even after just running. Now it won't start at all. It is a 94 sundance duster with a 3.0 engine

Optional Information:
1994 Chrysler duster 3.0

Already Tried:
turning the engine over and it won't fire
