Okay, I own a 2003 Honda Civic EX. The car has about 117,000 miles on it, and I've noticed that for the last 4 months the car vibrates when its in 1st gear. It happens when I first start to accelerate. It vibrates like crazy for a couple seconds from a dead stop. It also happens a little bit when I'm accelerating in 2nd gear, but not nearly as noticeable as in 1st gear. Does anyone have any idea what could be causing this?

 

What are you idling at?

 

hmm could it be either a motor mount or a transmission mount?
