🟡 Mazda CX-5 2.0 SkyActiv-G carbon buildup stutter

Mazda CX-5 2014
Safe to Drive?
⚠️ Drive with Caution
Urgency Level
🟢 Low Priority

Rough idle and stumbling on acceleration developing gradually after 80,000 km on the Mazda CX-5 2.0 SkyActiv-G petrol. Direct injection means fuel never washes the intake valves. Carbon deposits accumulate on the back of the intake valves, disrupting airflow. Walnut blasting by a specialist at 80,000-100,000 km intervals is the definitive solution. Chemical induction cleaning provides temporary improvement. Mazda recommends using 98 RON fuel to slow deposit formation.
