Got a fiat stilo 2002 5door 1.2 16v and today the engine management light came on and On the dashboard screen it says engine fault but the car still drives like a dream no problems at all. With the engine /filter cover the're is a melted hole at the bottom of the air filter box and when driving it sounds like a aftermarket air filter but with that could it be possible that the engine light is to do with the maf air flow sensor

Please post Stilo technical issues in Stilo section of the forum here: www.fiatforum.com/stilo
