2013 Cadillac ATS4 Misfire, Running Rough, Hard To Start 2.0l Turbo

Описание: Today we have a 2013 Cadillac ATS4 that is hard to start, runs rough, and misfires really bad. Let's see if we can get to the bottom of this and try fix this car. Around 24:26 I look at calibration data. There was a tsb for engine knocking and to update the ecu but the update was already done, somehow the video got lost.
