Advice about pipes into plenum???

[mjh500]

I have two smallish ruber pipes coming out of the o/s inner wing along with air/con pipe,which go into the plenum on the o/s in front of the stepper. Can anyone tell me what these pipes do and where they go to? The reason i ask is because the one nearest the stepper looks to have been removed and still has the jubilee fitted but just floating about in the wind. The Metal pipe coming out of the plunum has a rubber push on sealed pipe. Anyone know what is going on here,does this pipe go somewhere else or has someone pulled this pipe off for some reason and blocked the plenum. Any help please cos bible not helping. Thanks...

I am now very unhappy because since re-conecting this pipe to plenum i have had a strong smell of petrol when driving about. The car at first was running fine, did about 60 miles and all seemed normal, untill the engine started to tick over a bit low and try to cut out. This got a little worse and started doing it nearly all the time and now cutting out. She starts back up every time and might be ok for about 10 mins but the problem strikes again. I have cleaned stepper, recently changed the leads and taken this pipe back off and put the blank back on the plenum, no better!! Can any one help...

I have had a play about with the car today and have removed the carbon can which looks brand new and cheked the electrical plug which also looks ok. I have looked in the bible to see when the solenoid for the carbon can has power going to it. There does'nt seem to be any power going to it when the ignition is switched on or when the engine is running, only .5 of a volt. I have also taken the roll over valve out and am presuming the pipe going from the valve goes straight to the carbon can. If it does then it is either blocked or there is something else the pipe goes through because i cant blow or suck through it. I am wondering if this may be the problem. Im sorry if i might be getting on everyones t#ts about this but i am determined to get to the bottom of it. Thanks for all recent comments or any i hopefully recieve for this.
