Thank you all,
Before replaced the throttle sensor, the idle slowly goes down to 0 and engine
Off. Then I tried to replaced the sensor, but I didn't taking off the battery.
After that, I turn the engine on the Idle goes up to normal position. I'm really feel
Good, but after test drive for around 5 minutes the engine slowly went down to 0 and off.
Do you think I might really kill the sensor? The battery went down to 10volts, I hold the gas for 20 minutes the battery increasing up to 12.47 volts. So, I think the
Battery any the alternator are fine. What else do I need to replace?

Thank you all again for the help...

    With the engine running the voltage at the battery needs to be at least 13.5 to 14 volts!! Have a mechanic check the charging system before any more work is done!

    Another note is the battery voltage has to be normal or the computer and the sensors will not function properly. The relearn procedure is also affected.
