Deposits form in every fuel system, but the amount and how quickly they form depends on the quality of fuel and oil you use, your driving style and engine type. GDI (gasoline direct injection) engine intake valves are prone to rapid deposit buildup because they never get cooled or washed with fuel. Deposits form in as few as 5,000 to 10,000 miles, restricting proper airflow and increasing operating temps.
Symptoms of dirty intake valves include:
Hard starting
Rough idle
Poor acceleration
Reduced fuel economy
Power loss
Excess emissions
