I unlocked the PCM at a local store here and the guy has unlocked more than 100 srt PCM's and when he runs it on DIMsport it shows that it's unlocked and everything is fine. When the PCM is hooked back to the car, the car starts misfiring and coil #6 switches off and comes back after 1-2 mins for 10 secs and then switches off again.. O2 sensors shows faulty as well. The car is dealer maintained and never had issues with the car. Car has 80k kms. This happened exactly after the pcm unlock.

Car was basically running perfectly fine, then parked, removed the pcm, unlocked it and all this stuff happened.

Any thoughts?
