Not sure what has changed, but all of a sudden my acceleration feels a little rough. Not over the top rough, but not silky smooth like it always has been. I notice it most if I push the car with some quick acceleration. For instance, if I am on the freeway going 50 MPH and then punch it to get to 80 MPH, I notice a little feedback on the steering wheel, but more so in the acceleration. Mileage has still stayed about the same, tire pressures all look correct and no uneven tire wear. Not sure what it could be. Car has about 5k on it.
