    I found the 'T' and it ends at the valve, there is an open connection with a small piece of hose on it but nothing that runs all the way back to the fuel tank ??? it just ends.... is there a chance this might be the cause of the hesitation ?

    That's not helping you at all, since it appears to be bleeding in unmetered air into the throttle body.

    So you at least need to find the hose that runs to the gas tank, and connect that to the charcoal canister and to the throttle body. You can eliminate the purge control valve if you want, because it will be fine to purge all the time.

    If you don't have the gas tank vent line connected to the charcoal canister, there is the very real possibility of fire, because the gas tank vent line can contain liquid gasoline in addition to vapors at any time. (Gas vapor, of course, is explosive.)

    The canister needs to be vented because otherwise it will get saturated and then the car will smell like gas most of the time.

    So what I'm saying is that the only way to connect this is the right way, anything else is too dangerous.

    There are three nylon fuel lines that run under the body on the passenger side - the fuel pressure line, the fuel return line, and the vapor line. iirc, the nylon vapor line changes to rubber approximately where the nylon fuel lines change to the braided fuel lines as they run up to the engine. I believe the rubber hose runs alongside the passenger side frame rail up to the radiator support where it runs across to that T that you were describing earlier.

    Not having a canister (or not seeing one) where would/should it mount?

    Located the canister and also believe I located the line back to the tank (?); 2 questions :
    1. How can I access the top of the canister? I tried removing the airbox, no luck .... I'm guessing remove drivers tire and wheel well liner ?
    2. There is a line that goes across the radiator support and right below the area of the container there is a purple 't' with no fitting on it point up towards engine, is this where I attach the 'out' line from from the canister ? I have not had a chance to trace the line.

    I think that's the right one - it should be on the bottom left of the radiator support. One line runs left to the charcoal canister, one line runs right and ends up at the gas tank, and the third goes up to the port on the throttle body. The canister purge solenoid is on the third of those lines.

    directly under the radiator, inside one of those plastic Ts or tubes, the passage is quite small and is intended to be a restrictor to meter how much vapor gets sucked from the tank. that orifice gets clogged preventing the tank from venting. easily cleaned with a small wire or whatever.
