It has forgot how to idle due to battery swap! It will fix itself, just let it run awhile, turn on ac ect. There is an idle relearn but it will perform this on it's own. Be patient! Don' put any more parts on until you drive it some. Now if you need the relearn after running and driving it, let us know but it should be ok!
