I recently replaced my engine mounts to try and fix the problem I was having with vibration at idle. After having the shop replace the mounts the vibration is almost gone when the engine is warm but when the engine is cold (or very cold, I'm in Wisconsin) the car will vibrate bad until it warms up. The whole dash shakes and the rear view looks like I have really good subs... Lol. Once the car warms up it gradually goes away. Any ideas on possible solutions to this issue?
