sorry for the short english. by btw i meant "by the way"
Anyway, when there is some repair or cleaning done to the intake system, or sensor cleaning, throttle body service, etc, the ECU needs to be reset so that the new idling parameters are recalculated by the ECU. This way it relearns the amount of fuel injected for different conditions of the engine. Yours is exi and if its has a original engine, there will be no oxygen sensor in it. So the final mixture is set by the adjustment knob behind the glove box. If its not disturbed, i will suggest NOT to touch it as its factory set. First cater all the other problems.
Hows is your throttle body health/cleanliness? And injectors?
