It all started about 8mths ago.I bought a used engine out of a 01 sebring to swap into my stratus figuring it would be easy since everything was identical boy was I wrong.It has codes p1391 and 0356 it has a constant miss as soon as it starts which btw it fires right up no hard start at all i haved replaced pcm,ecm,coils,plugs,injectors,alternator,cam and crank sensors 3 times each ive tested the wires for both and they are good ive looked at the cam gear and tone ring they match.Im at the last thing i think can be wrong Im going to check the tone wheel on the flex plate which is worst case so im asking for any other options if anyone has any as I have alot of time and a whole whole lot of money invested in this.......pls help
