think i found my reply.. since i dont hae emissions or inspections here. i think i can do what this guy did..
quote{Do you guys have to run a canister? One of the things I have done in the past is to measure the resistance of the purge valve and fit a resister
in the electrical plug, then remove the canister. The need for the resister is to fool the ecu into thinking that the purge valve is still conected so
it won't log an error code or put the engine light on.}

where exactly are you?
if you dont want to fit the canister just block off the port on the throttle body and leave the purge valve connected to the ECU as per stock just
with no hoses on it
the ECU doent know its not doing anything it just needs to know its there and connected

Joel, im in the usa, states, arkansas state. i think they allow anything and everything go up and down the highway in this state, wierd, because i'd
moved from another state which had strict smog, emissions and inspections was long list of stuff. thanks mate for the info on evap.. i will do that
soon.

hoses or is it completely vacuum type purge valve? if you have a picture it would help me out where to find the purge valve

i havent had a chance to disect a TT engine
on mine its mounted on the underside of the manifold on the powersteering pump side
it shouldnt be hard to find, theres a rubber vacum hose going from it to the throttle body
just trace the hose from the throttle body back, they usually run through the hard line jungle underneath the manifold

i have my power steering pump off, because im not going to use it.. i even took off that radiator reservoir off from the side. air intake hose off
there.. so all thats wide open.. i even traced the smallest metal line out.. it goes to the top of my throttle body. i can not find nothing in that
side on the intake manifold of under it thats anything other than fuel hoses running back n forth.. nothing is screwed in the intake there or
anything. that line that goes from top of throttle body to underneath the intake to the other side.. theres nothing on it.. . it goes straight
through to the other side without stopping anywheres. its puzzling to me.
