Chrysler Repair: P1391 code, camshaft position sensor, crankshaft position sensor

Question
Hello Kevin, I have a 2001 chrysler sebring 4 door sedan with the 2.4 dohc engine.  The check ingine light came on and it gave me a P1391 code.  I replaced the cam shaft sensor and misfiring continued.  I then replaced the crank shaft sensor and the misfiring continued.  I took off the crank shaft sensor and put back on the old one because it was a $70 part and it wasnt the problem.  I also put new plugs and wires on the car.  The car is still running very very rough because of the misfires and giving me the P1391 code still.  I don't know where to go to from here.  I have replaced both sensors and the problem continues.  Nothing I have done has helped the problem at all.  If you could lead my in the right direction I would greatly appreciate it.  I don't want to have to take it in to the shop and have them search around for what could be a lot of money for me to pay.  Thank you for your time and effort.

Ben
