An intresting read. I will try my new n75 first and see how that fairs. If that fails then I will have to do some more investigating. Its not everytime it happens to me but, every now and then say 1 every 3 months it seems to happen to me.
Im hoping it is the n75 valve rather than the map but we'll just have to wait and see. Thanks for the input
Yeh mine was everytime, all the time. Could've lived with once every 3 months. Yeh would try the N75 first, just interesting its at a similar rpm to when mine did it. Hope the N75 fixes it for you.
