Well......I just took my 98' Boxster out of storage yesterday. As I previously wrote, I got the code for the evaporation system (P0446) as I was driving the car to its winter storage back in December.

At that time I read the code and cleared it figuring I would deal with it in the spring, which is now. So after taking it out of its 4 months of storage I drive it about 75 miles, hoping to re-set all of the car's sensors/codes to the "ready" state. So I drove it for about another 50 miles with no CEL.

Does that mean my issue has "magically fixed itself"?...I doubt that.
Could enough fuel have evaporated in 4 months of storage?....I have no idea.
Is one of the valves in the system "sticking" intermittently?....I have no clue.

I suppose all I can do now is just continue to drive the car and see if the CEL ever comes on again rather than letting my "indi" investigate it further.......but I definitely WILL NOT try to top off my fuel tank in the future. Maybe I'll be lucky.....
