I have replaced the Camshaft Postion Sensor, Crankshaft Postion Sensor.

Question

We have replaced the camshaft position sensor, crankshaft position sensor, the ignition coil and the spark plugs.  The jeep runs great once it is warmed up.  But, first thing in the morning when it starts it runs rough and then it dies.  Then it takes about 3 or 4 more times to start and then it is fine.  We are still getting the P1391 code and the engine light is still on.

Any other ideas??
