i m driving L 2.
and have the similar problem like urs.
bad ideling, sometimes RMP go up to 2K.
my foreman help me to remove the thermostat.flush the radiator.
cox sometime the sludge will stuck in chock there.

i dont think its a good idea of removing the thermostat as it keeps ur engine at a certain temperature for better performance....

mine happen to be the same bro...but its very rare....

 

[speed2horizon]

aiyar... idling problem kah....

Ficd/throttle body/isc/stepper motor.. all same thing mar...

Unless your throttle body cannot close properly, but still won;t happen suddenly...

If airflow sensor kong, then got check engine light.

Bro try check your O2 sensor. It was happened to me last time when my O2 sensor wire putus. After replace it and adjust the TPS, my car has back to normal.

fazid bro...long time no hear. howzit goin' man?
I had tat same shit b4. try reset battery 1st. Does it get worst if aircond turned on? if it is...try swap stepper motor. or have a go with MUT for error checking.
