Check spark plugs, wires, fuel filter etc. Then I would suggest taking a look at your your MAF sensor.

plugs and wires have approx 3k miles on them, fuel filter replaced approx 2k miles ago, new upstream o2, new MAF (mine came apart in 2 pieces when I tried to take it out), new IAT sensor.

I did notice it is around 45-48 mph, if I start up incline is when I notice it most. May check into MAF as well. MY MPG is shoy lucky if I get 16-17mpg combo driving city/hwy
