    hi, could anyone help me, my zafira for the last month has been making a whistling noise when i accelerate, it sounds like its coming from the engine area, if i take my foot off the accelerater it stops but as soon as i press it again its back, it usually only does it when going over 40mph, sounds abit like a turbo but it hasnt got one. if i rev the engine with car in neutral it doesnt happen, its starting to annoy me now, its a 1.8 petrol. thanks

    hi, where would i find these bolts that may need tightening, i only know how to do the simple things when it comes to cars.
    a mechanic took the car out today and said he couldnt hear anything, think i might take it back and i'll drive.
