violent jerk on cold starts
i've had my 06 limited for 5 years now. over the past month or so it's been doing this weird thing. on cold starts, there is a very violent jerk(movement) that comes from the engine. it's only there for a split second but is very noticeable when sitting in the vehicle. once the engine is warm, it will not do it again. any ideas?
