So in tune up, weak spark plugs were diagnosed By Toyota dealership. Got them changed and now the car has touched 11 km/ litre.
Getting the spark plugs was a hassle though in Karachi
!
Toyota dealership 1 price 3000/ pcs (IMC)
Toyota dealership 2 price 2200/pcs (dubai import)
Open market shops prices ranged from 1000 to 1800/-
And all are GENUINE!
