I am sure this is right if the light actually means something.

ON our 91 Spider, the check engine light sometimes (e.g., two or three times 
a year, only in Summer) will go on for a few seconds, sometimes even twice in 
a day, when the conditions are aligned just right, which means going a 
certain speed (I think it's between 60 and 80 mph) and the engine is hot, and 
we're going up a hill (but not too steep a hill) at speed, and perhaps other 
things are involved but haven't been noticed.  Since it goes out in a few 
seconds and stays out, and this has happened a few times over a few years 
with no other clues or problems, I assume it is some kind of transient 
reading that has to do with the indicator light circuit itself and not 
something it's supposed to be indicating.  Once upon a time I had a similar 
issue with the break pad wear indicator light on the GTV6.  False alarms.  
It's possible.

GTV6 just passed smog, and pretty well, too!  Not bad for an old trout!
