New Annoying Problem
When I'm in a stand still like a red light.
As I release the brake SLOWLY the car starts to shake.
Not really a bad shake but you can feel it.
It shakes the whole car, but once I fully release the brake the shake stops. If I where to keep releasing the brake slow n slow I could make the car shake pretty bad.
Any ideas what this could be?
How do I check to see if the motor mounts are ok without taking them off?
Brakes and rotors look really good incase some asks.

tech here, mostly likely the shaking is caused from a bad spark plug wire. just one going bad can make the whole car shake like that at idle. a way to check motor mounts is pop the hood, set e-brake, put car in drive, hold foot on brake, press accel as if you were power braking the car, but do it just to the point before the tires break loose. do a couple quick power brakes like that and if the mounts are bad you'll noiceably see the motor lift up and make and popping noise when its coming back down...alot of the time. but chaces are your problem is from wires. how many miles? and also with the motor mounts, you can take the front under body panel off and crawl underneath or just look, and with that panel off you should be able to see the mounts and you can see if you see any dark colored fluid coming out, or running down the side of the mount. hope this helps.

Zayed, car has no code errors. And I did disconnect the battery two days ago.
To the tech, I will check the motor mounts as you suggested. But just incase you miss understood me.
The car in park ANDi in drive while holding down the brake has no shake.
It only shakes when I release the brake a little at a time. If I'm in drive and I let go the brake fast and give it gas the car don't shake. But, if I let go the brake slowly it shakes.
Any other ideas?
Thanks

Yesterday I checked the engine mounts and the driver side is really bad. Going to order the mounts and two ignition wires next week. Hopefully this will solve the shaking.

If your are changing both engine mounts, you may consider doing the transmission mount at the tail end of the box at the same time.
