Dodge Caravan 1996 3.0 Automatic

I have problems accelerating with speed since I accelerate and starts coughing and throwing it but being in p o n works the engine well, could they help me?

The first thing I do is turn on the A/C, the headlights, and the speedometer. If it jerks and the idle is unstable, it's either a spark plug or a coil. The best thing to do is scan it to find out which cylinders are misfiring, then check the spark plugs and coils for those cylinders. I think your coil might be leaking, but check it and let me know.
