I recently bought a 92 Honda Civic. I have driven it for about 2 months now. Last week, for about 7 seconds or so; my car began to shake.(I was driving, and was slowing down to a turn) The car began to shake again a couple of days ago for another couple of seconds. What could this be and what needs to be done? To whomeveer reads this and answers, I greatly appreciate it. Take Care.
