Sometimes when I stand at idle (every 800 km), the engine seems to vibrate more than usual. but RPM is normal and no check engine. i notice that when happened, throttle position in 83.1 not 13.3 as normal.
about 20km after that engine and throttle goes to normal position and no vibrate.
picture below describe throttle position.

 

I'm a little puzzled by the RPM when it shows 13 and the speed &.RPM when shows 80+

 

This is normal idle

 

If at idle and it should show around 13 and it shows something else, sounds like a malfunctioning throttle position sensor.

 

Sorry for the delay, but I was waiting for it to happen
Attached are pictures of the normal idle and shakes idle

 

If you look closely at the throttle position and engine RPM , you will see the last picture posted shows the throttle practically wide open and yet the RPM is at idle position.
Something not right with throttle position sensor reading.

 

how to check the sensor?
this is another data from idle when no shake

 

Your gauge readings are already telling you something is wrong with the sensor. Just have it checked out or just replace it.

 

ok
change "throttle position sensor" or throttle body?
can you check part number for sensor?

 

35100-2a900 part number for throttle body, but cannot find tps for car
