its most probably a vacuum leak. your just going to have to search for the hissing.

get a gas blow lamp, don't light it but turn the gas on. move it around where the noise is coming from, when it finds the leak the gas will be drawn in and the revs should increase

Same as above really just have a good hunt around for split pipes, is that running gear in a micra, if so your a star as thats what i am getting towards doind when the silvy( if it ever) dies, bet its a bit nippy when its right and sorted.

Probably the brake servo having a leak

Right i have sussed one problem.

after one nights logical thinking and a good nights sleep, i thought of the answer and i was right.

Its the air flow sensor (the little silver hitachi box), i know should have checked this first after the problems micra's have.

so just gotta find a new one now, anyone got one for sale?

cheers Paul

Yeah that would make sense I guess. I actually misread your first post and thought it was running fine but you got a hiss after you turned it off lol

Silviagod is breaking one at the moment

in the video it was hissing while its running

The engine isn't running in the vid, the key was turned so there was power but not running?

could it be the fuel flowing through?
