2002 Honda Civic hearing a sound

Can you descibe it better? Does it happen when you come to a stop, accelerate, turn, at certain speeds, or all the time? Does it make the sound and vibrate in park or at a stop? What is the sound, how bad is the vibrating? Can you feel it in the steering wheel, or under you?

Thank you for replying, I really need your help, I hear it when iam going back with my car (when I put R) also when I put P in these to cases the vibraiting is obvious also it vibrates when I put (D) but not as much as in the previous cases. I am sure that it is not because of the wheels maybe there is a problem in the chair of the engine.

I'm sorry, but I'm not a real mechanic and doubt I can help, but I will try to. Just know that my suggestions are just light advise and my chances of being wrong are far greater than of being right. I do know a little about cars though and am most curious of the noise and vibrating accruing more in park than drive. It could be you have a loss of horse power (more on that later) and the engine is in more stress in park than when you give it lots of gas. Also you usually don't go too fast in reverse so that theory can still hold. Does it get real bad at a stop light and even worse with the ac on? I am sure it is not your tires or rotors because it does it in park. I also doubt it is you motor mount because of the age of your car, but that is still possible. Can you pop your hood, start the car and see how much your engine shakes? How are you in maintaining your engines performance? Has it had a tune up, new plugs and wires? Has it had a new air filter or fuel filter? Have you put injector clean in with your gas? How many miles are on it? Have you noticed a lack in performance or its get up and go, or is it just a noise and shacking problem? What does it sound like? You could drive to advanced or auto zone where they will pull the code on your car for free, and may tell you what your problem could be. Get back with me and I'll try to help more. If you get it fixed let us know how.
