Rough Idle fix for the 2012 GMC Sierra 1500! The GMC Sierra 1500 with 6.2L gas engine was acting up this week. These vehicles have been known to experience VVT issues and such. While driving home I noticed the engine running rough. Check engine light codes – P0011, P0101, P0068
Upgraded from the Canon R5 to the Canon R5 Mark II in 2024. My thoughts so far...
