Not sure if this is normal
When driving ,sometime i here what sounds like a relief valve blowing off. It only does it for a second or two and it happens most often when driving slow up hill. It does it more often nowand i don't remember it doing it when it was brand new. i only have about 8000 miles on the truck but it is almost a year old. Also the fuel mileage seams to have gone down . I don't know if the 2 have any thing to do with each other or if the noise is normal?
