There is a noticeable rattle noise when car stop with transmission in D or R, but the noise go away if change gear to N or Park. the Engine speed will go up to 1K RPM in N or P, and 800 RPM with D or R gear. The car also feel some vibration when driving in more than 20 mph. Change Spark Plug and Transmission Fluid does not help. Does it came from the bad Engine Mount or drive shift mount? Any info is great appreciated!

Have you checked all of the exaust heat sheilds? You may have one that has broken a bolt and the drivetrain flex in gear at a stop causes it to rattle.
The Idle numbers you posted sound right. That is where mine idles.

The vibration could be from multiple sources. I would have the U-joints looked at, as well as the engine and transmission mounts. The rattle could be due to a busted mount allowing the engine to shift more than it should.

How to check the engine-mount? U-joint?

Does U-joint can be grease? Does anyone replace the U-joint at what mileage?
