It may recalibrate itself. The computers recalibrate every 1,000 miles. Also, because of the unique sparkplugs in these engines there may be some fouling or you may have made a mistake in the replacement process. If it doesn't go away soon take it to a dealership. If you don't you could cause expensive damage to your engine and exhaust systems.

Hello, the idle speed is controlled by the computer, there is no adjustment, what you can do is to clean the inside of the throttle body:

Remove the intake hose from the T/Body, disconnect the battery, use a can of air intake/throttle body cleaner and a brush, open the throttle all the way and clean the carbon out, put the hose back and reconnect the battery, start the engine and keep the rpm up until it clears out, drive it for about 15 minutes, about 90% of the time this fixes low idle.

Engine mounts control the engine movement but it may be because the idle rpm is too low. Most of these cars idle at 950 -1000 rpms.

You don't need to change the spark plugs since it has only 31.5 K. The plugs should last 60K. There is a an adjustment at the gas cable end at engine to increase the idle a little bit. You can increase rpm at idle to 600 RPM. Since your RPM at idle is low that why it is shaking at idle, red lights. Let me know it it is shaking at high speed ( 2500 RPM)
