2006 Envoy runs like new
I just wanted to tell you my 2006 Envoy was knocking, had rough idle and very poor gas mileage. It's as though something was choking my engine to death. I took it to Thronhill Dealership and they performed the BG Induction Service. My 2006 Envoy runs like a new one. Wish I had heard about this product sooner!
Thank You!
