ENGINE VIBRATION

2010 Ford Focus • 63,000 miles

I bought my focus used about 2 years ago, Its been a great car. Recently however I've been noticing a strong vibration whenever I sit in park neutral or if I just idle, as soon as I accelerate or even coast it is not noticeable. It's worse if the engine is cold, but it does not get much better if the engine is warm. I have not noticed any sort of drop in mileage or performance. Other friends who have "small" cars have had similar problems. Ive heard some say that engine mounts are commonly the suspect. Just looking for some thoughts on if that might be the problem and if there are ways I can determine what is the cause is. I'm used to doing some basic mechanic work at home on my own. I have a vide variety of tools and equipment. I would prefer to do this on my own if its a possibility.

Check the motor and trans mounts and make sure the rubber sections are not collapsed. That is my first guess. Also, let me know if you have noticed that the engine is running worse or giving you any trouble.

How do I tell if they are collapsed? And there are three mounts total?

There are a couple things you can do. First, just inspect them to see if there appears to be any excessive wear to them.

Also, and this will take a helper, you can check to see by running the engine. Open the hood, apply the parking brake, and do the following: 1) Have a helper start the engine

2) Once started, place the vehicle in drive.

3) Keeping one foot on the brake so the car can't move, give a little throttle to the engine so it places the mounts under a load.

4) While this is happening, you watch if the motor raises on one side excessively.

5) Do the same thing in reverse.

It is normal for the engine to move an inch or so, but if it is moving more than that, at least one of the mounts is bad.

Let me know what you find.

I did that, and didnt see anything significant, the engine raised slightly as a whole then rotated a small bit, but neither side or direction was noticeably worse than the other.
