Hey folks, new member here. I have a 2008, 3.7L V6 Jeep Commander that is experiencing a weird problem. When I press the gas pedal all the way down to the floor, the speedometer shows that I am only moving about 30Mph, however, it feels as if I am moving half that speed. Obviously, I have a problem but I am wondering if anyone here has experienced the same issue? I don't even know where to begin with searching for the problem (using the search function), because the problem description is too long. Please help out a noob. Thanks.
