Yeah, GDI engines need to decarbonize more often I suppose. I've done it once a few weeks ago, pretty dirty.
De-carbonized already? How old your car? Another thing you De-carbonized the pistons also or only the valves. There is someone doing the valve cleaning only....

My car quite old already, it is 2008 car. Decarbonize everything. It was done by a Toyota/Lexus specialist in Port Klang (Multiplex Auto). They had post their advertisement here as well since last year.
