I have a 1994 Mazda 323 Protege. It has very low miles and runs well. The isue is that when I'm stopped, with the brakes applied(under load) there is vibration. It does not happen in nuetral or while driving. It only happens with the brakes applied. Any ideas?

Thanks greg

 

My first and best guess would be a bad or weak engine mount combined w/a low idle.

 

Thanks. If it is a bad or weak engine mount, is it a huge job to change the mount?

 

I highly doubt it. In a car like that it shgould be nothing more than basic mechanics using basic hand tools.
