Two reasons for engine vibrating:
1 The engine tuning has not been done correctly. Correct the flow of fuel.
2 The engine mountings are loose. Tighten all the mounting bolts.

    I changed my spark plugs and I know I did all of that correctly. I may have loose engine mounts though, thanks

Why does my car start to vibrate when i'm at a stop light but not when i drive


Automatic right? You probably notice the vibration stops when you put the car in neutral when stopped - It is not a major issue - more annoying then anything. If it is rough idling it could be a number of things which are usually rectified with a major service.

I believe that I have either a bad transmission mount or mounts, and possible a bad motor mount or mounts because the car vibrates in drive while running and also vibrates in neutral while running but not...


Get a friend to open the hood and look at the engine go up or down in the engine compartment when the brakes are firmly applied and switching between reverse and drive. Look for the motor mounts for behavior where tears exist in the rubber.

I have an annoying vibration-rattle in the back on


While I am not trully certain, it may be an exhaust heat shield. These, from time to time, may loose a weld and vibrate. Often a "tinny" type of noise. If the noise is more of a heavy thump or such this may be something mechanically loose.
I do hope this may have assisted you,
Tom

Enging vibrating at idle


1) It is very possible your engine mounts can be worn, but

2) the vibration you feel may be also due to the idle itself degrading to the point that the car is shaking. Does the engine sound like it is getting ready to die? what is the engine rpm when you feel the vibration? You may just have a dirty throttle body. In this case, clean the throttle body plate and bore and the problem will go away.

3) did the problem seem to come on suddenly or gradually, if gradually, you may just need some plugs and/or wires, and/or cap/ignition rotor, etc. (a tune up)

4) Also, do you only feel the vibration when the AC system is on?

5) there are some other reasons for abnormal engine vibration at idle, but the above are some of the most common, and simpler to repair.

All the best with the repair!

Toyota corolla 1.6 1997 vibration after clutch change


Try checking the engine/transmission mounts, one of them may not have been reinstalled properly, or worn out, causing a vibration. If the car is able to move with the new clutch, and it seems to work, I wouldn't say the clutch was put in wrong. Also check the wires around the engine/transmission, you may have knocked something loose as well.
Hope this helps

Car vibrates at idle.


you may have a pulley out of balance. ie harmonic balancer, steering pump, alternator. try increasing idle, set it at 850-900.
