2.5 na swapped the motor and now it has a dead miss on cylinders 2 and 4? I swapped plug wires and plugs and coil pack and cam position sensor and crank sensor. Any other thoughts to fix it 

I'm no expert so, hope others will respond;

on some swaps, I think you have to move the cam gears over from the old engine.

You should tell us what year/vehicle and what engine went into it.

If you straight swapped an 00-04 EJ25 then you probably need to swap the drivers side cam and crank sprockets from the original engine to the new one. 

07 impreza non turbo.the motor came out of a 08 wagon non turbo. It was a 130k mile that ran and drove it had been in a accident.  We did head gaskets,front n rear seals,intake gaskets,new plugsnwires, we put the cam gears from the 07 on it we also had to swap some of the sensors the 07 motor to the 08 motor so that the harness would connect to them and we did new timing belt n water pump
