^^ i am not sure if the LEC model has ECU already. kung meron, ECU ang nagcocontrol ng idle nyan.

kung wala, may iniikot dyan sa may distributor.

thank you po!
Ano ba ang ECU?
na try ko na po yung inikot sa may distributor pero hindi po nagbabago yung idle

My Tagalog is not so good, but when it comes to any car, whether injection, carbs, etc, your idle is controlled by your idle control valve, which is also hooked up to your alternator to detect load on the electrical circuits and increase or decrease the rpms accordingly.

If you also have an air leak in your intake side this further shows up on idle and under load.

Please do not go directly to the ecu if your vehicle has one, as this should be a last resort.

A good auto tech can check your car in about 15mins to see what the prob is in general and then take it from there.
