    Unstable RPM on neutral

    Hey,

    I have a Fabia 2004 1.2htp and for the last few weeks it wont hold RPM on neutral when you throttle. I need it to hold between 2500 and 3200r for 15seconds to pass emissions on NCT. Replaced throttle body, checked injectors, im totally stuck. Any ideas or experience?


    Thanks!

    I am having similar problem. I have OBDii bluetooth device indicating that the MAP sensor is the issue.
    I have located it but it is tight behing the cranc case and I cannot get it off.
    Any advice would be much appreciated.
    I have also cleaned the lambda sensor and the EGR sensor which resolved other error codes but I need to resolve the MAP issue - I would expect it just needs a clean so if anyone has successfully removed one before please share how
