Right my car has started the beloved - bobbing up and down idle trick

like its bogging down, Now the engine had already been run this morning and got upto temperature

left about an hour, and the temp guage comfirmed some heat remained upto startup again

Started it up - boggy up and down idle, decided to start disconnecting sensors to see which affects the running

I unplugged the canister purge valve, no effect, plugged it back in, and it stopped instantly

Is it possible that the valve its a case of a sticking open valve? remove and clean and refit time?

okay - FES tested
its actuating nicely, and maximum mixture is only 6%
Averages 2 to 3% so its not the purge valve
