Nice sharing, we should stick to the maintenace schedule of the car given in owner's manual, At 100,000km service I replaced idle pully, surpentine belt,spark plug, one faulty ignition wire,air and fuel filter, coolant, differential oil,gear box oil,seal and filter,AC filter under the dash board,Master brake cylinder and vacuum booster, engine timing and ECU mapping was checked, now car is running very nice.
