Bill, thanks for following up with the link to Intrepid Overland's
article on the evaporative canister:

https://intrepidoverland.com/eec-aka-the-charcoal-canister/

Lots of good detail there.  The article explains the canister is not a
wear item, but a relatively complex system purges the collected fuel
vapor using air flow produced by intake vacuum, only when the throttle
is above idle.  It says quirks in that system can cause idle surging and
hard hot starts, mostly due to a worn throttle body.

Well worth reading the whole article.  Thanks again!
