    I have a similar problem the car vibrates almost violently when stopped and the ac is on but in park it seems to calm down a bit. I have tried tweaking the Idle control valve but it only worked for a little while.

In this situation, I found out that the top latch of the front hood rattled against the bottom metal hood latch at low idle. A thin rubber strip with adhesive on one side, cut to just fit over the bottom metal loop where the top latch rests on does for temporary, but quiet fix. Just make sure the the rubber strip allows the latch to lock properly. Push down firmly on the front hood and try prying the hood open with just your fingers to check. Again, this is temporary as the adhesive may get dirty and fall off during multiple maintenance access to your engine.

It may be the catalytic converter or exhaust pipe heat shield(s), with the park brake set and ac on at ilde push on the sheet metal shields with a broom stick and see if the noise stops. It works best with someone in the car to listen for noise changes.

My mazda 626 2002 is overheating we have replaced the resevoir and the caps and its still doing it its fine when driving than when you come to an idle it starts to heat up again and than will go back down...

it sounds like the radiator fans are not coming on. Check the fuses and relays for the fans. there is a temperature switch to control when the fan(s) comes on. If you have AC then the fans should come on when you turn on the AC.

1999 Mazda 626 is blowing small black particles our of the ac vent. What is this and how do I fix it?

Most likely the air filter located in under the dashboard has rotted apart. This will continue until all the pieces have blown out or you change the filter.
