    Default DBW issues

    I have a LQ4 was a DBC but I converted over to a DBW with a TAC controller part number 12588923 and its pedal assembly. It works till it hits 85% throttle and then it closes the throttle blade and will not open till you cycle power on the ECM. I did a complete reflash of the ecm with a 2003 LQ4 and DBW. Also it has an idle issue but the engine is all stock. I have added the tune file and a log file if anyone can look at them and show me what might be going on with it.
