03 Chrysler 300m
 

I put a 99 3.5 motor in my 03 Chrysler 300m and now it want run right it takes like 5 or 6 trys to start and it want go past 2 rpms please help me if you know what my problem is

codes in teh computer? and when it wont start what is the engine doing?

It just cranks but want start I have changed cam and crank sensors and checked timing on it it's good still hard to start and want go past 2 1/2 rpm what is going on with this car

well it being a 99 engine in a 03 car the computer were different the 99 would be an SBEC and the 03 and NGC to which teh cam tone wheel and fly wheel are different.

What parts do I need to change to hopefully make this work properly

Also I did change the flywheel to the 03 just not the cam tone wheel is that my problem I know every once in the while it will run normal and go past the 2 1/2 rpm
