Unfortunately Engine anti-pollution system defective can mean almost anything. You need to get the fault code read to be more specific.
Last time I had it my mechanic read the fault code which identified the throttle potentiometer. He squirted some electrical grease onto it and cleared the code, and it been fine since (he didn't charge me).
