Thanks Hey bazz, ive just had probs with my fiesta and revving probs and i got told it was the idle vavle. I removed it today, cleaned it with carb cleaner and it works a treat...you mite wna try it. Other to that check the sensors are all on correctly...mainly your mass air flow sensor. goodluck Nat Quote Link to comment Share on other sites More sharing options...
