I just discovered that because my 98' Boxster has what Illinois calls "Expanded Antique" license plates I am exempt from the "every two years" emissions tests, which I would have surely failed......so once spring comes and I can start driving again I plan on driving it for a few weeks to see if the CEL (which I cleared using my code reader) reappears.
I had this same code about 3 years ago and just kept clearing it....then at some point it just stopped lighting up the CEL with that code and for the last few yrs its been fine.....UNTIL I mistakenly really topped off the tank for storage.
That's why I asked IF the trapped fuel in the canister will evaporate on its own, thinking thats what happened a few yrs ago.
Thx
