CVT Oil Change, if it hasn't been done yet
Spark plugs cleaning (should be done with petrol or TB cleaning spray and cloth, NO abrasives (wire brush or sandpaper)
if abrasives were used in previous "tunings" then these may need to be changed.
Cat cleaning? Haven't needed on 135k km driven grande yet. But yes, every once in a while, I do an italian tuneup where I drive it at high rpms for 10-15 minutes at least. It burns up and clears any deposits that might have accumulated in catcon. This vehicle doesn't require hioctane nor I could see any noticable performance, fuel economy improvement.
Infact unless the vehicle knocks, the hioctane fuel blends in Pakistan contains additives that are antiknocking but they block the cat con in long run.
Get the suspension checked, the z links usually go out at this mileage if driving on rough roads and bigger wheels.
