I have 1995 camry, I completed turn-up for my car, car runs very smooth, except it vibrates abnormally at idle speed, tachometer shows 800 rpm, which is within specs. If I speed up idle speed to 1000-1100 rpm , the vibration is gone. What is wrong? Thanks in advance. Regards! Ho

I'm afraid the dampening effect on the motor mounts has failed. The most common fix is replacing the front mount near radiator, and the "dog bone" mount near the right strut tower. This will help a lot but not completely. Every mount should be done to make it like new again. The back one is almost imposible if done in the driveway, but you can do the first ones mentioned. All you need is a floor jack to support the engine, and some basic tools to guide the new mount into position. Make sure to use a block of wood when supporting under the oil pan.
This is not cheap parts from a dealer. Nearly 200 bucks, but well worth it. Aftermarket mounts don't seem to be as smooth. Just FYI.
