Hey fellowz..woundering if u can help me out..got dis massive problem with my 4th gen vtir lude. The problem is my car keeps on reving up and down on idle by it self, from say about 800-1300revs continously. Just up & down & up & down. My mate said it might be my injectors are dirty so petrol dosent go down probably. Ive just recently changed my fuel filter. If any one out dare can help it would be great..thanks guyz.=]
