Hi. I am looking to replace O2 sensors in a 2015 GMC Terrain, I was wondering if the computer needed to be taken to the dealership for a proper re-learn or is this just something I can replace myself?
Hey all, I’ve got a 2018 GMC Terrain 1.6L TD. Looking to get emissions deletes as the warranty is up and we are having some emissions issues. Looking for insight where parts can be purchased from and who does tuning for these?
