Replaced the vehicles computer and injector harness. Vehicle shutters while driving? Also sounds like the motor is missing. There are no codes and no engine light lite? While in park the engine runs rough like a cyclinder is not firing?

Check the injectors to see if they are working. (You can unplug then one-at-a-time to see if that makes a difference in the way it runs). If you unplg one and it doesn't change the running of the engine then that's the one whic is giving you the miss at idle.

Have you checked/changed the spark plugs?

Check for vacuum leaks.

Sometimes the intake manifold will leak, causing extra air to be drawn in to the system. You can check for leaks around the perimeter of the intake gasket (with the engine running) by spraying carb/throttle cleaner around its edges. If a leak is found the engine speed will either increase or decrease. BE VERY CAREFUL AS CARB/THROTTLE CLEANER IS FLAMMABLE
