My truck has been getting under 16mpg latley. I was getting like 22 with it. Only mods i have done to it is the muffler is taken off and it has a airaid filter. but these i have had done since i got it. i have a 6" lift but i am running the stock tires/wheels in the winter.
It has also been ideling a bit hi once in a while. I notice al this when it started to get under like 45 outsde. Could it be because i removed the muffler??
