I just bought a pre-owned 2004 Mystichrome Cobra Coupe... I love it and can't stop looking at it. My problem is that when I drive at a low RPM (in gears 1-3) I lightly accelerate and here a sort of clicking noise until about 2600 RPM. One more thing... When I put it in 1st from a dead stop the car jerks just a tiny bit. Any solutions or ideas? Thanks guys.
