I've had the car for about 2 years. Yes, It is serviced regularly, I've got about 2k kilometers before my next service. No, but I told the mechanic to check the spark plugs, he said if there's an issue with the spark plug, the engine should miss (he test drove it and encountered the issue). His suggestion was to dismount the engine and check the clutch plate, flywheel etc. (Recently replaced clutch plate)
What does an OBD scan do? I think I'll do that scan and then let him dismount the engine and whatnot
