I have a 2011 Silverado with 125k miles, bought the truck with 90k and found out the problems with the active fuel management on these model trucks so I put a programmer in the truck to delete those hoping it would help make the engine last longer. It’s is now burning oil, has a puff of white smoke when it starts after sitting for more than 3-4 hours, and the fuel alcohol sensor acts up when it’s cold outside making the truck start rough and idle rough for about 30 seconds. Is anyone else having all these problems?
