As I am figuring now I'm getting about 13-14 mpg. I've done nothing different and do not know why I'm seeing this. On Saturday I changed my plugs and cleaned my MAF Sensor. since then I filled up and have drove 90 miles today and have used a 1/4 of a tank.
Up to now I have had no issues with my truck at all. Any help would be appreciated.
Just wondering, how did you clean your MAF Sensor? Wipe it with a rag, use any kind of cleaning solvent on it? Any chance you damaged the MAF or the wires attached to it during the cleaning process? Does the engine run & idle now as it did before you did the maintenance on it? (ie not running rough or bouncing idle, etc)
I do agree with others that winter blend gas will decrease MPG. Also agree with bodio about hooking your truck up to techstream and checking for any codes/faults.
