^^^ Yes. It's the same engine as the RWD IS250. It's the problem with direct injection engine. IS350 uses direct PORT injection which avoid this carbon build-up.

Always gas Premium (91+ Octane) and some say use Shell V power or Chevron because they have extra cleaner in the gas to help with the problem.
