Little filter thing

[LEONMEX]

On the 105e it has a pipe coming off the inlet manifold to a little matel filter,it has 12v going to it from the coil & earthed through the chassis. The car has servo brakes also run from a union on the inlet manifold. Ive disconnected it from the coil & it made no difference. It is new & has been added as an afteemarket part. Any ideas as to what this is? if not im going to take it off & put the breather back on the manifold as thats where it should be. Cheers,leon.

[Mr Sam]

is there a vacuum gauge in the car

[LEONMEX]

no vacum gauge,it goes to nothing just a bit of pipe off the manifold with this filter hanging off it & a wire. I was just abit concerned it might make it run lean as its sucking air into the inlet manifold but when i disconnected it it makes no difference.

Is it one of those eco valve things thats meant to improve throttle response blah blah blah, if it is, bin it !!

[LEONMEX]

Did wonder if it was one of those fse valve things thats ment to improve performance? Think your right though steve & ill take it off & put the breather back where it should be

Anti run on valve? It gets a live feed when the engine runs and is 'shut'. If you disconnect the electrical feed to it then it will remain open and youll run lean and end up with a really high idle speed.

Ill get it off tomo & get a pic up

wot emu said it,s called an anti diesel kit ,stops pre ignition when you switch off by sucking air out of the inlet manifold
