My 2010 mitsubishi endeavor has an Idle surge, does anyone know if it could be related to what feels like a shudder under load. I have a code reader with the torque app, can anyone tell me what the procedure is to reset the TCS or if I need to take it to a shop for them to do it? I also will clean the throttle body and unhook the neg terminal to do It..will it relearn on its own? I can take it apart to check the gears too
