You have got to be kidding me. I have had my Jeep for 9 years and attributed my severe coasting drag to overly large tires and boxed aerodynamics. Tonight I shut off my hill start assist, and now all of a sudden my Jeep will coast!!! I can not believe it! My tach drops to like zero when I let off the gas and it just coasts like it’s almost in neutral. That will change the gas mileage for me!! Thank you so much for the tip! I found this thread because I’m having trouble with my throttle control cable. I’m also investing in a sprint booster.
