200 might be sick again, then again.....

I can't help, but can you Americanize this e-mail?  =)

This ONLY happen on a long trip?  That would point to a heat-soak issue.
Sadly, it might not be easily fixable until next summer when the temps climb
back up.  The throttle position sensor is easy to check for a dead spot, or
non-linear output.  It's a simple potentiometer.  It would be helpful to get
the codes.  After all, when the CEL light is illuminated, there IS a code
stored at that moment.

Good luck.  And speak American next time.  ;-)
