Suzuki Vitara 1.4 Boosterjet carbon intake valve deposit
Rough idle and hesitation on acceleration developing after 60,000-80,000 km on the Suzuki Vitara 1.4 Boosterjet. As a direct injection engine, the intake valves accumulate carbon deposits not washed away by fuel. An intake cleaning service using chemical induction cleaner through the throttle body improves symptoms. A walnut blasting service by a specialist completely removes deposits. Suzuki recommends using premium 95 RON or higher fuel to reduce deposit formation rate.
