Hey does anyone else feel the floor shake a little when they floor it in there 4Runner? Its like when I add a lot of gas, the whole car feels like its vibrating a little. Anyway, I have had a 1998 and 2000 4runner, and they both do it.
did you check engine/trans. mounts ? I know my truck has a lot of vibration during accell, especially under load. my car shudders on letting the clutch out. Just a thought.
