Carbon buildup on intake valves

Engine Internal
Ignition, coils, and jerky takeoff (shuddering)
Often reported
Symptoms of hesitation, unresponsiveness, and jerking during acceleration are reported; these are attributed to worn spark plugs, coil packs, or high-pressure injection management issues.
