Bhai its a minor issue, dont worry and please dont go for any big resolution like some one might say coils are gone , injectors are gone these all are ********, LIANA is an modern engine you cant say whats wrong untill you go for step by step resolution. According to me you might have got error code on your sensor due to oil or bad fuel uncomplete combustion etc etc.. These are few things you must do as initial testing.
1) Remove battery terminal for few minutes or there is computer under dashboard above golve box but it is deligate it must be unplugged in proper manner or you will lose **** fixing it, remove terminals leave it few minute then plug it back leave it few minute 10-15 start the car and let it be on idle for 10 minutes and this is how computer re caliberates it self.
2) If test 1 didnt fix you prob then second thing you must take out all four spark plugs and ask mechanic to check and suggest if one cylinder is missfiring plug is quite bad or etc etc.
3) if test 2 seams ok then go for throttle body cleaning.
4) Still didnt work go for SHIMS JOB.
