Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
What i suggest you do first is clean out the throttle body, this is a very common issue where over time the throttle body gets carboned up and causes the IAC ,(Idle Control Valve) to also carbon up and cause airflow issues ..
On some lancer models you will not have a IAC, but have a full electronic controlled throttle body .
if so this should also be cleaned but with care that parts cleaner does not get sprayed on the black plastic control .
The video is a idea of what to do and maybe the same as your in the lancer

Think you most likely just have the throttle body without the IAC ,this is okay makes it easier to clean ..
If you do have the one with the IAC remove and clean .
