Mohd. Zaheer: Rough idle and hiccups in my lancer 2014, the car probably had some major accident... below are the solutions after the research : 1) spark plugs (I have changed them but the problem persists)
2) Ignition coils
3) throttle and air valve cleaning
4) mass flow sensor cleaning
5) fuel filter replacement
6) cleaning of fuel injectors
Now in saudi Arabia the mechanics have no experience and they fool you. .. can somebody tell is there a precise way to diagnose the issue first.. #Scotty Kilmer Scotty kilmer
