From your first 3 points i dont know some how have a feeling that water has gone inside your clutch assembly.That can be seen by the fact that rpm keeps increasing but the car does not accelerate.The water is causing the clutch to slip.Car struggles and jerks is another sign of water entering the clutch
About the misfiring and missing dont worry about that little water would have entered the delco and could have caused the misfire.Avoid taking the car in water filled arears for sometime.Do some wheelspins to burn a moist layer of the clutch.Things will get back to normal
They same thing happened in my 800 and showed the same syptoms as yours.But after about 12 days everything went back to normal.
