    It's near the right rear of the engine on top of the engine. Need to remove the cover to locate.

    Well from the response he gave I would say no, he did not say there were two.

    The canister is back there (by the tank) but not the valve.

    The Purge solenoid is in the engine compartment, the Vent Valve solenoid is on the canister.

    Re: Canister Vent Valve Solenoid

    Sorry, sent you to the wrong place. The vent valve is a twist to remove but to get to the canister you have to remove the rear frame (per SM). That involves the exhaust, rear prop shaft, shocks, brake lines etc. etc., over 20 steps. Maybe some real skinny arms might work. Better make real sure that is what needs replacing before starting this project.

    Re: Canister Vent Valve Solenoid

    That's the SM drawing of the end of the canister after the rear frame has been removed. I think it's forward of the fuel tank towards the left side. Again, why do you think you need to replace it?

    Well after I put gas and have replaced the gas cap, the car don't start. after 2 times starting, there are no more issues starting but just a rough idle, its only when I put gas, I have taken the gas cap off and never replaced and it turns on and not as rough of a idle. So I'm just lost now

    Re: Canister Vent Valve Solenoid

    So, if you get gas and replace the gas cap, it won't start but after a couple tries it will? Then starts OK until you get gas again but has a rough idle. If you leave the cap off after getting gas, it starts and idle is not as rough? Please confirm all or part of this so we can help.

    Also, when you fill the tank, do you stop when the pump first shuts off or do you keep adding until it won't take any more? VERY IMPORTANT!

    Ok everything you have said is correct the idle is just not as rough as when the cap is put back on, And no I never fill it up the tank to the max always half or almost full.

    Re: Canister Vent Valve Solenoid

    Have you checked for DTCs , pending or history? If not, do. If you have a fuel pressure gauge, Hook it up and check pressure when it won't start. A short to voltage in the signal circuit of the CKP sensor will prevent starting and not set a DTC. Leaking injectors can flood the engine. An easy check would be to inspect and test all the vacuum and similar lines for continence, considering the age of the car.
    Let's keep after this until we get it.
