This a common problem that every Chrysler customer is suffering.The company should do something regarding this.But for mean while you can go and meet the dealer of this car compny.He might help you.

 

sounds like a faulty idle air control valve that fits on the inlet manifold

 

The P1391 says that one signal or the other (there are two signals) that come from an electronic sensor is disappearing momentarily at least 20 times in trip, during two consecutive trips.It suggests that either the sensor or its wiring or the engine part that the sensor observes is in some way faultly.It suggests that the wires to the sensor or the part,or the sensor itself could be faulty and might be identified by visual inspection or testing with an electronic test device.The sensors are needed to time the sparking of the spark plugs and the injection of fuel.
In and of itself it is not of great concern until the signal it totally lost,in which case the engine will not run.So to me it would mean to be aware that this is happening and if the engine becomes notably losing its power or momentarily jerking that you need to find out which signal is missing and why because it may soon stop running.

Do NOT, repeat, do NOT put anything in the transmission (torque converter) other than the fluid recommended by the manufacturer.
