Problem with a AUDI A3 2.0L FSi 2003

Poor running at idle and emissions readings checked indicated an air leak. No air leaks found, suspect fault due to sticking valves. 

The fault was cured by cleaning the intake system with Forté Valve Cleaner as per instructions, Forté Clean and Protect (Forté Oil System Protector and Forté Advanced Formula Motor Flush) carried out and Forté Advanced Formula Gas Treatment added to the fuel tank. 

After treatment the vehicle was running smoothly on idle and the emission readings restored.
