My 05 Stratus with 155k miles started sputtering while accelerating a couple of weeks ago and hard to start. It stalled this week while driving on the interstate and won't re-start. The OBD code is P0300-multiple cylinder misfires and my research shows a list of possible causes including spark plugs and wires, egr valve, camshaft and crankshaft position sensors, etc.
Can anyone give suggestions on most likely causes and solutions.

 

my 98 Avenger did about the same thing... same code... mine turned out to be the EGR valve...
