did you clean the throttle by yourself?

you need to reset the ECU to let the idle control value to readjust.

多谢師兄，我想問reset ECU是断開電池15分鐘，定要用車房電腦reset?

I did this to reset......

Do the idle learn procedure whenever you do any of these actions:

-replace ECM/PCM
-Reset ECM/PCM
-Update ECM/PCM
-Replace or clean throttle body

Procedure

Make sure all electrical items (a/c, audio, lights, etc) are off.
Reset the ECM/PCM (pulling the power by unplugging the battery works well).
Turn the ignition switch ON (II), and wait 2 seconds.
Start the engine. Hold the engine speed at 3,000 rpm without load (in park or neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194 F (90 C).
Let the engine idle for about 5 minutes with the throttle closed. (NOTE: if the fan comes on, do not include its running time in the 5 minutes.
The biggest this I can say: be patient. If you don't get it just right, you may need to do the procedure a second time. Also, keep in mind that an erractic idle can also be caused by a vacuum leak.

600-800rpm when the car is warm up.
