  1. I have an 08 silverado with 212000 miles. It still runs and drives great. I was wondering if anyone has ever tried to disable the active fuel management on a silverado with over 200000 miles. I was just wondering if it would do more harm than good
  2. I just bought an 08 silverado. It has the 5.3 afm flex fuel engine. I have heard that there have been some issues using these new ac delco filters on gm motors. I would just like to know if these will damage my engine if I use them.
