Problem with a VAUXHALL ZAFIRA 1.9L CDTi 2007

Poor throttle response and performance. Suspect fault due to contamination build-up in the intake system. 

The fault was cured by cleaning the intake system using the Forté Power-Clean Diesel Intake Cleaner and carrying out an extended road test. After the road test, the throttle response and performance were restored.
