i have replaced all 6 coils and plugs. also changed the harness that runs to the 3 rear injectors and crank sensor. i even replaced the crank (pos), crank(REF), and cam sensors. resetted the ecu many times but comes right back when i restart. only symptoms is the cars hesitate on take off and idles rough in gear on occasion. car pulls and revs fine. smooth and strong. just at take off when the car idles rough then the car would hesitate. when the car is idling smoothly the car takes off smooth. motor just recently swapped in. i check for vacum leak, none. loose or broken wires, none. any ideas or help will be appreciated.
