Question about 2003 Chevrolet Silverado 1500
When I am in 2WD, it sounds like it is in 4WD. When I am on snow or ice, only rear wheels are driving. When I put in 4WD, everything works just fine. I noticed increased fuel consumption on the last couple of tanks.
Not sure what you are concerned about here, probably fuel economy i'm guessing? you might consider purchasing a "scangauge II" which will give you a digital readout of about every sensor on your truck, including fuel consumption, ignition timing, knock ******, MAP, intatke temp, trans temp, etc.
it also reads/resets codes, i have found it to be a great diagnosis gauge/tool
