I have a 2004 Subaru Forrester that I have taken very good care of. It has 188k miles on it. I've recently noticed that my gas pedal feels a bit rough under my foot. It usually feels smoother. Is this a precursor to something ie. the TRANSMISSION, or maybe just a wheel imbalance? FYI - there doesn't seem to be any slipping or hesitation when I increase acceleration. Thanks, Sue B.
