I was thinking T/LLR was my problem but swapping did nothing...

Now wondering if its the purge valve..when I checked a few month ago was all good, pulsing nicely w/ hot engine. Now it isnt pulsing at all and seems stuck open, would give sign of vac leak. Does anyone know if purge valve always runs on warm engine?

Also anyone have a handy list of the vacuum line part #s? I want to replace all the fittings just in case and it would be a b***h to pull them all, measure, and then wait while the order processes
