Carbon Canister Question

[tydon]

i know is not needed was wondering how i can eliminate it completely from under the manifold. using a v3/4 inlet manifold i was thinking of leaving the purge control solenoid in the green/black plug under the iacv one of the hoses goes to a vaccum nipple and the other to the pipes running under manifold to carbon canister i was wondering since theirs a pipe coming from up near the fuelfilter which usually plugs into the other end of the carbon canister could i run that hose to the purge control solenoid. getting rid of the alloy pipes going to the carbon canister.

or can i block off the other nipple on the purge control solenoid and block off the hose up near the fuelfilter which goes on the other end of canister.

let the tank line breathe somewhere down the firewall. unplug the solenoid and throw it. strip all the rest of it out and plug the vacuum up off the manifold.

so i can strip the wires in the manifold for the plug? wont it throw a cell?

[Guest]

try running it with it unplugged first thats what i did. i think wrxonp had v3 and he didnt get cel either.

thats what I was thinking, when I removed mine I left the solenoid plugged in but not plumbed up to anything so the ECU still thinks its working.

[Guest]

def didnt on mine. its not hard to check. dont know why it would its just for emissions.

[WRXONP]

nope definatly wont throw a CEL

remove everything completely -

[tydon]

sweet cheers guys

[WRXONP]

oh make sure u let the gas tank breather hose breathe - dont block it - its sweet to just remove the hose and let it breathe - allways done it like that with no issues what so ever

[LAZLO]

would this be the same for mitsi cedia??

[WRXONP]

yup all cars are the same - some just dont have a purge solenoid

[LAZLO]

ok hopefully this is whats wrong with our cedia,it wont rev over 4000rpm it hits 4000 then starts choking,we put in a tester reader thing and it said carbon canister

[WRXONP]

hmm a carbon canister should not stop a car revving lol - all it does is purge the fuel vapours into the combustion process - think of it as plumbing back - for emmissions

[LAZLO]

oh trudat,i dont know why the dumb thing came up with carbon canister,oh well just gonna leave it as is for now lol thanks brad

[WRXONP]

did u run a scan tool on it ? if it came up with a code for carbon canister - the only way the ecu would know if theres a problem with the carbon canister is if the purge solenoid is un plugged or faulty - but it shouldnt stop it revving

[Guest]

is it gdi? what was the code and proper description? what brad saids right

if cel is on it sounds like its going into limp mode

I used the one way valve off the carbon canister (little grey thing inline) on the end of the breather line. fuel vapour is way too flammable to leave the hose open.

breather line? is that the hose coming from the chassis? so i should put that grey valve on the end and leave it unblocked

[Guest]

if you put the one way valve in all you are doing is blocking it up or leaving it open anyway. if you poke it right down the firewall theres nothing to ignite it anyway. your fuel cap should breathe out the cap anyway but when ever i gas up my tank is still pressurized and my breathers open...up to you really its been done either way by people on here and havent heard of cars blown up iraqi styles yet.

LOL id hope not haha

hm - if you have sparks in yo engine bay - i think somethings up !!!

ive allways just removed the rubber hose and left the hose open to vent for many many years - like i said never had an issue - have weldid in engine bays before - no issues

[LAZLO]

yeah we used a scan tool,i dont know what the problem is,but it doesnt go over 4000 so its pretty much just a slow drive all the way

[WRXONP]

i saw a mates mitsi a few years ago- was a vr4 legnum - in limp mode it couldnt rev over 3k - check engine light was on

what ever comes up on the scan tool - fix that - if it says carbon canister - look at the vac lines and see if theres a solenoid on the vac lines - check its plugged in and check wiring is all i can think of

[Guest]

anything gdi soots up really bad maybe its clogged vac solenoid. theyre pretty electronic them mitzis. if its anything like the chariot/grandisd fly by wire. whatever it is whether its big or not its pulled limp mode which is why its only doing 4k. what code did it throw? go buy some throttle body cleaner and empty a can into it.

Just had a look and that my Carbon Canister has been removed, one side has been blocked up and the other hose with the big grey thing is just left there.
