Sorry to hear bout the bad luck.. I've decided that before i do anything to drastic I'm going to take my truck back to the mechanic and have him do a tune up. it hasn't had one since it left the plant floor. I will let ya know what happens from there. I read up on several possible issues for the vibrations. Everything from faulty fuel lines to gunkked up filters and spark plugs.
#373 of 374 Silverado 2011 5.3 Crew Cab 4x2 Active Fuel Mgnt. by string2

I now have about 5,000 mi. on my Silverado. Just filled up AGAIN with 21.2 gallons of gasoline. My gauge showed 321 miles since last fill up. My Active fuel management won't work above 60-65 MPH, therefor I don't get the benefit from the Active Fuel Management at normal highway driving around 70 mph. GM has looked at it and assures me that it's operating normal dispite their misleading epa window sticker 15 city 21 highway.I get about 15 city 16 on level highway above 65 MPH. Not loaded and I don't have a heavy foot. gas - Shell, Exxon, Chevron
321 miles divided by 21.2 gallons gas = 15.14 MPG city miles 50% highway 50%
Since the Active fuel Management is not designed to work above 65 MPH on level highway, I can't get the fuel savings at the highway speed of 70 -72 MPH. I don't know why they designed it that way, but GM says that's normal. Are they lying to me ?
