I was driving on the highway today when, after slowing for traffic, I stepped on the gas again and my car had a pulsating/shaking feeling. When I took my foot off the gas it stopped, but when I tried to speed up again it did it again. It almost felt as if I had a flat tire, but when I got off the highway and slowed down there were no problems. When I got home I didn't have a flat. Any suggestions on what I should try before calling the dealer?
