If that were mine I would disconnect the battery and unplug and reseat every connector touched. Because the engine ECU is right there, I suspect something is not seated as it was before the Alt failure.

Did you replace the battery too?
What is the cold sitting battery voltage, idle, and 2000 RPM voltage all accessories off?

the car is very shaky once started like it wants to cut off once the temp raises a little then it runs but its misfiring so I cant go above 40 miles an hour... the battery is good the altenator is good I think something else is causing this
