Arrghhh!

Check engine light came on again. Third time in six weeks, and as before, it is the P1441 code. I know its the evap/recirculation system, and I know for sure that it wasn't a loose gas cap. Anybody have any bright ideas about what parts I should look at next, or how I should troubleshoot?

All three times, it has happened at the same place under the same conditions. It kicks on at the end of a downhill, which I take in 2nd gear. I shift up to drive, make a sharp left, and BAM, light goes on. All three time on a day of average temp and humidity. Code P1441 all three times.

Any pointers would be greatly appreciated.
